GENERAL INFORMATION

The BayTech PS-4 print server models ar e high performance network
print servers that support up t o four peripherals including print er s,
modems, and other asynchronous devices. The PS-4A has four parallel
ports, the PS-4C has four serial ports, and the PS-4E has t wo parallel
and two serial ports. The BayTech LaserShare Net work PS- MIO is a
network print server card which installs into the MIO slot of the HP
LaserJet Series IIISi and Series 4/4Si laser printers. The BayTech print
server is typically used as an alternative to a value-added process (VAP)
or NetWare loadable module (NLM) print server. These unit s em ulat e
PSERVER operation and eliminate the need to r un PSERVER on your
file servers or on dedicated workstations.

Each BayTech print server complies with either the IEEE 802. 3 Et her net
standard or the IEEE 802.5 T oken Ring standard. The IEEE 802.3
models may be modified to support t he 802.2 frame type. All models are
compatible with file servers running Novell NetWare 3.X X and 4.XX using
normal NetWare commands and utilit ies (i.e., PCONSOLE, CAPTURE,
and NPRINT). You may use an Ether net 10BASE2 (thin coax), 10BASE­T (twisted pair), or a DB-9/RJ-11 (Token Ring) network interface
depending on the specific model pur chased.

The BayTech print server services up to 32 print queues distributed on as
many as 32 file servers and does not requir e user configuration to locate
its file servers. Communication with each file server is independent of
communication with any other file server. An optional " Pr eferred Server"
mode of operation instr uct s the print server to login to a single file server
and read a list of other file servers containing print q ueues for it to
service. This is helpful f or lar ge networks with many file servers or a
network with a bridge connected.

2

The PS-4C and PS-4E support EI A- 232 or EIA-422 serial interf ace
allowing you to locate parallel printers up to 1000 f eet away when using
the BayTech Tran-x® SP-01 high speed ser ial t o parallel converter. The
serial ports featur e m aximum output speeds up to 460K bps. Dial-out or
dial-in modem communication is accomplished thr ough BayTech's utility
software that supports EXTENDED BIOS 14 calls. Software packages
tested for compatibility are Mirror III® LAN, Procomm Plus® for networks,
and pcANYW HERE/ L AN



.

Once the BayTech print server has been installed and configured,
network users are able to print t o attached printers in the same manner
as they would to any other Novell print server using NetWare print
commands. The method in which print queues are serviced is similar to
PSERVER (i.e., queue ser vice mode) .

The BayTech print server may be progr am m ed to update its queue
information automatically or manually when changes are made to queue
assignments. Utilit y software is supplied to configur e all per ipher al ports
and to inform all file servers on the network that the BayTech pr int ser ver
has been added. In addition, you may change the print ser ver nam e with
this utility. The utility will transfer all queue and printer information to t he
new name eliminating the time consum ing print server insertion/definition
required by PCONSOLE.

Figure 1

shows an example of a PS-4E used in a Novell based network
using 10BASE2 or 10BASE-T cabling . This example shows 2 printers, a
plotter, and a modem connected to a PS-4E.

IMPORTANT:

In this manual, we assume you know some basic
information about Novell based network s including basic DOS
commands, your network's operat ing system, the NetWare version
number, and the basic funct ions of Novell's PCONSOLE program. I f you
have any questions regarding t he Novell PCONSO LE program, please
refer to your NetWare document ation.

INSTALLATION/OPERATION OVERVIEW

This section provides basic set up instructions for print server installation
and operation. We will refer to specif ic sections in this manual for more
in-depth instructions on installat ion, operation, and configurat ion. Please
review the following procedure:

Step Instructions

1 GENERAL

Determine what BayTech Print Server model you are installing. The model num ber is
specified on the lower right corner of the rear panel. The model number will have a
hyphenated suffix indicating the network interf ace type. This suffix will be one of the
following:

-CX

(for 10BASE2 thin coax),

-TP

(for 10BASE-T twisted pair), or

-TR

(for

token ring).
Identify which ports are s eri al and whic h are paral l el . Serial ports have RJ-45 modul ar

connectors and parallel ports have DB-25 female connectors. The PS-4A has f our
parallel ports, the P S-4C has four serial ports, and the PS-4E has two parallel and two
serial ports. The Las erS hare PS-MIO installs directly into the MIO slot of the HP
Laserjet IIISi or HP Laserjet 4/4Si printer and does not have parallel or serial ports. If
you are installing a LaserS hare P S-MIO, install the unit into the MIO slot of t he pri nter
as described in

Section 4.5

and proceed to Step 2.

Determine what devices will connect to t he print server and if these devices will
connect as serial or paral l el . Typical devices incl ude pri nters, plotters, modems, or
Tran-x high speed serial-to-parallel converters.

2 CABLING

Cable your print server to the network as described in

Section 5

. If you are install i ng a
LaserShare PS-MIO, proceed to Step 3. Modular adapters are typic al l y required to
connect serial printers, plotters, and modems to the pri nt server. You may connec t a
Tran-x high speed serial to parallel converter to a serial port which will allow a parallel
printer to be located up to 1000 feet away from the print server. Please see

Appendix

A

for the required serial adapter and cable pinouts.

NOTE:

If you will be connecting a Tran-x high speed serial-to-parallel converter to a

serial port on the print server, you must change t he serial interface for t he port to EIA-

422. Please see

Section 4.4

.

Parallel ports require a s tandard male to centronics cable to connect a paral lel printer
to the print server.

Step Instructions

3 PRINT SERVER INSTALLATION TO THE NETWORK

Once the BayTech print s erver has been physically connect ed t o the network, it must
be added to the network via software. The print server may be added to the network
and print queues assigned t o the printer ports using Novell P CONSOLE or BayTech's
utility program (PSQMGR). The basic steps to install the print server on the network
are listed below.

a. Log on to the network as a supervis or.
b. Load PCONSOLE or PSQMGR.
c. I nsert the BayTech print server i nto the list of availabl e pri nt servers.

NOTE:

Changes to the default print server name must be made using
PSQMGR or BCON. On networks with m any file servers or with bridges or
routers, it m ay be advantageous to use "Preferred Server" operation (see

Section 7.6.7. 4

).

d. Install and configure where necessary the print server ports that will be

servicing print queues.

NOTE:

Changes to the serial port parameters (baud rate, word size, et c.),
must be conf i gured us i ng PSQMGR or BCON.

e. Define the print queues to be serviced by the print server (if not already

defined).

f. Assign the pri nt server ports to servic e t he appropri ate print queues.
g. Reset the print server using the BayTech utility software or by cycling power.

See

Section 6

for step-by-step network installation instructions using PCONSOLE or

Section 7.7

if using PSQMGR.

Section 7.8

discusses how to c hange the print server
name and/or serial port parameters using BCON. P ri nting is typically accomplished
using Novell's CAPTURE command, NPRINT command, or directly f rom PCONSOLE.

4 MODEM COMMUNICATION

NOTE:

If you are installi ng a LaserShare PS-MIO, skip t hi s step.

If a serial port on the pri nt server is to be used for modem communication, you m ust
use PSQMGR to configure the port as a modem port.

a. Networks users that will be accessing a connected modem for dial-out must

be assigned as

virtual users

. Actual dial-out operation is performed usi ng
the BayTech MSHELL program i n conjunction with a network based
communications package suc h as Procomm P l us® for networks. The
communications package m ust support EXTENDED BIOS 14 CA LLS.

Section 8.1

discusses di al -out modem communication in more detail.

b. Dial-in communication is acc omplished by loading the BayTech MSHELL

program on a local network "hos t" workstation. A remote user may access
the network by first dial i ng i n t o the local modem connected to the print
server. Then a virtual connec t i on i s established between the local modem
and the host workstation. Third party software such as
pcANYWHERE/LAN



allows the remote user to access the network through

the local host workstation.

Section 8.2

discusses di al -i n modem

communication in more detail.

INSTALLATION

IMPORTANT:

W hen you are installing the BayTech print server, we
assume that you are familiar with Novell printing concept s such as pr int
servers and print queue operation. Please r efer to your Novell NetWare
documentation for m or e information on network print ing concepts.

This section discusses basic installation instructions which include
unpacking, the software utility diskette, power considerations (PS- 4A, PS­4C, and PS-4E only), hardware configur at ion for the serial peripheral
ports (PS-4C and PS-4E only), installation into the MIO slot of t he pr inter
(PS-MIO only), and factory default parameters.

Section 5

discusses

cabling,

Section 6

discusses print server installation using PCONSO LE,

and

Section 7

discusses the various commands provided on the utility

diskette and installat ion using PSQMGR.
Before you proceed with installation, you should determine the nam es of

the print queues to be serviced by the BayTech print ser ver. For the PS­4A, PS-4C, and PS-4E, you should determine t he num ber and type of
printers that will connect to the unit.



UNPACKING

After opening t he box, check the packing list that com es with your
BayTech print server to ensure that you have received all components
and to determine the specif ic BayTech pr int server model number you
have purchased. At a minimum, you should have received the unit, an
external power supply (PS-4A, PS-4C, and PS-4E models only), a T­connector for the 10BASE2 ( coaxial) m odels, and this manual with any
applicable addendums. Determine the default print server name which is
located on the bottom of the unit. Also check the unit to m ake certain
that it did not receive damage dur ing shipping. If it em s ar e m issing or
damage did occur, please contact BayTech technical support at 1-800­523-2702.



BAYTECH SOFTWARE UTILITY DISKETTE

BayTech provides utility software to configure the unique settings of your
BayTech print server. These include the ser ial par am et er s and virt ual
circuit connection for t he peripheral ports (PS-4C and PS-4E only), t h e
update operation mode, the print server name, queue service interval,
and resetting the unit. I n addition, software is provided for modem
communication using virtual circ uit s and third-party EXTENDED BI O S 14
calls communications software.

IMPORTANT:

Copy the BayTech original diskette ont o a blank diskette
and store the original in a safe place. Refer to your operating system's
manual for copying instruct ions.

The software utilit y disk et te provided with your BayTech Print Server
contains a single zipped file: INSTALL.EXE. To install the BayTech
utility software on your network, first log in as a supervisor and use the
DOS COPY command to copy INST ALL ont o a public dir e ct or y on a file
server which the supervisor and users have access to. Next, type

INSTALL

from the public subdirect or y prom pt . This command will
expand seven files onto the public subdirectory: PSQMGR.EXE,
BCON.EXE, MSHELL.EXE, DIAL.EXE, MOPEN.EX E, MCLOSE.EXE and
BAY.TCH.

PSQMGR is a menu-driven configur ation program equivalent to Novell
PCONSOLE. PSQMGR is used to prog ram the unique feat ures of the
BayTech print server as well as set up other print servers, m anage print
queues, control network pr inting, and view information about network
printing. BCON is a command line utility that perfo r m s cer tain functions
of the PSQMGR program from a DOS prompt. The BAY.T CH file is
called by the PSQMGR program when it is loaded.

14

MSHELL is a memory resident program used f or dial-out and dial-in
modem communication. DIAL allows modem select ion from a menu for
dial-out modem communication and is used t o assign workstation IDs for
dial-in modem communication. T he MOPEN and MCLOSE programs are
used for dial-out modem com m unication to select a network modem and
disconnect from the m odem r espectively. The operational functionality of
the software is discussed in

This section does not pertain to the PS-MIO since this unit draws
its power from the LaserJet printer. If you are installing a PS-MIO, please
proceed to

Section 4.5

.

IMPORTANT:

Do not power up your BayTech print server until all

external cables have been connected (see

Section 5

). If you will be using
PCONSOLE, do not power up the BayTech print server unt il after the unit
has been added to your network as a print server and the relevant pr int
queues assigned to it (see

Section 6

). If you will be using the BayTech

utilities (see

Section 7

), you must power up the BayTech print server af ter

all external cables have been connected.
The PS-4A, PS-4C, and PS- 4E m odels r equire external DC power. The

external power supply provided with your print server supplies 9 VDC at 1
A. To apply power, first plug t he DC jack of the external power supply
into the

POWER

receptacle on the rear of t he unit and then plug the AC
connector into an AC socket. Next, posit ion t he on/off switch on the rear
panel to the

ON

position. Power-on is indicated on the fr ont panel by the

illuminating of a green LED.

WARNING:

Do not connect or disconnect the DC jack from the BayTech
print server while the AC connector is plugged int o an AC socket. Power
should be disconnected anytime cables are to be installed or removed.
Make sure the power is disconnected before removing t he cover and
attempting to m ake any internal changes such as changing the EPRO M.

If you are installing a PS-4A, please proceed to

Section 4.6

.

PS-4C AND PS-4E: SERIAL INTERFACE

SELECTION

Serial ports on the PS-4C and PS-4E may use either EIA-232 or EIA-422
serial interface. The serial interface is configured via hardware jumper
settings. Most serial printers and plotters support EIA-232 serial interface
(default). This generally limits the serial speed and ma ximum cable
distance. EIA-422 serial interface allows you to run at high speeds (up to
460,800 bps) over long cable distances (up to 1000 feet). Some printer s
may be equipped with an EIA-422 port. BayTech supplies a high speed
EIA-422 serial to parallel converter (Tran-x SP-01) which would allow
your printer to operate in parallel up t o 1000 feet at 460,800 bps.

NOTE:

If you will be connecting a Tran-x high speed converter , you must
reconfigure t he ser ial int er face of the port( s) t o EIA-422. If you will be
connecting any EIA-232 serial printers, plotters, or modems, you must
use EIA-232 serial interface (default).

Serial interface selection should be done before any other hardware
installation such as connecting cables or applying power. Once you have
made any necessary changes for serial interface, you may review the
user-programm able features (see

Section 4.6

).

If you must reconf igure the serial interf ace for any of the peripheral port s
on the PS-4C or PS-4E, you will need a phillips-head screwdriver. Please
use the following instructions:

1.

IMPORTANT:

Remove power from the unit by first unplugging
the AC converter from the AC socket and then removing the DC
jack from t he

POWER

receptacle.

2. Remove the cover of the unit by first unscr ewing t he 2 scr ews
located on the front panel with the phillips- head scr ewdriver.
Next, remove the front panel and then slide the top panel off.

16

3. Refer to

Figure 2

below and locate the jumper locations for EI A­232/EIA-422 serial interface selection. The jumper locat ions ar e
adjacent to the respective serial ports . Each jumper location has
three pins: a center or common pin, a pin marked

232

, and a pin

marked

422

. Each port is configured for EIA-232 or EIA-422
serial interface by positioning four jumpers to connect t he
common pin and the

232

pin for EIA-232 (default) or the common

pin and the

422

pin for EIA-422.

IMPORTANT:

For each port, all jumpers must be installed either

to the

232

or

422

side for the desired serial interface.

Section 6

.

NOTE:

Even if the factory default settings are satisfactory, you
may still use the BayTech software utilities to add the BayTech
print server to the network. The primary advantage to using the
BayTech utility is that it automatically informs a ll selected file
servers the BayTech print server has been added. Otherwise, you
would have to update the desired file servers individually. Other
advantages of the BayTech utility software are described in

CABLING

Section 5.1

discusses the hardware interface to the network and

Section 5.2

explains how to cable your printers or plotters to the

PS-4A, PS-4C, or PS-4E.

CAUTION:

Power should be removed anytime cables are installed.



NETWORK INTERFACE

The network port of your BayTech print server is equipped with a
10BASE2 (coax) connector for - CX m odels, a 10BASE-T (modular)
connector for -TP models, or a DB-9F (STP)/ RJ- 11 ( UTP) connector for ­TR models. The specif ic net work interface type is indicated on the lower
right corner of the back panel. For example,

PS4E-CX

specifies a PS-4E

with a 10BASE2 coax network interface. See

Section 5.1.1

for network

interface instruct ions for -CX models,

Section 5.1.2

for -TP models, or

Section 5.1.3

for -TR m odels.

24

IMPORTANT:

BayTech 10BASE2 (-CX) and 10BASE-T (-TP) print
servers use a frame type of 802.3. If your network uses a frame
type other than 802.3 (e.g., Ethernet II or SNAP), you must load an
additional frame type for your network card in the file server. This
is accomplished via the LOAD command. Please refer to your
Netware System Administration documentation for more
information on loading a LAN driver more than once. You may
hardware configure the print server to support the 802.2 frame type
without the need to add another frame type to your file server. This
is done by removing the jumper at

JP2

. Once this jumper is
removed, the unit will only recognize 802.2 frames and will no
longer recognize 802.3 frames. Please see

10BASE-T (MODULAR) CONNECTION

If your network uses 10BASE-T, RJ-45 connectors, connect an RJ­45 cable between the modular

NETWORK

port and the network

hub. The modular

NETWORK

port is defined as DTE (i.e., Pin 1 is
TD+, Pin 2 is TD-, Pin 3 is RD+, and Pin 6 is RD-). Most RJ-45
network hubs will require a straight cable.

The

LINK

(link integrity) LED on the back panel will illuminate if
there is a good connection between the BayTech print server and
the hub.

If you are installing a PSMIO-TP, proceed to

Section 6

if using

PCONSOLE to add the unit to the network or

Section 7

if using the

BayTech software.
From the factory, 10BASE-T models come configured to use Un-

shielded Twisted Pair Cabling (UTP). If your application uses
Shielded Twisted Pair Cabling (STP), you must configure a jumper
on your print server. The required jumper number is

JP5

for the

PS-4A and PS-4E and/or

JP6

for the PS-4C.

PS-4C AND PS-4E: SERIAL PERIPHERAL
INTERFACE

IMPORTANT:

Before you proceed with cabling your serial peripherals to
the PS-4C or PS-4E, you must verif y that t he equipment supports either
EIA-232 or EIA-422 serial inter face. In addition, you must know the
connector type and the pin/signal definitions for your equipment . If you
wish to connect a parallel printer to the PS-4C, you must use a Tran-x
SP-01 serial-to-parallel converter. You may also use Tran-x on the serial
ports of the PS-4E to connect a parallel printer located mor e t han 25 feet
from the unit ( up t o 1000 feet).

Serial ports on the PS-4C and PS-4E have RJ-45 ( 8-wire) connectors
which accept RJ-11 (4-wire) or RJ-12 (6-wire) connectors.

Figure 9

and

Figure 10

on the following page are drawings of an RJ-45 receptacle and

plug. The pin/sig nal definition for each port is determined by the serial
interface you are using

.

Figure 9: RJ-45 Receptacle Figure 10: RJ-45 Plug

If the serial ports of the PS-4C or PS-4E are set for EIA-232 serial
interface (default) and you will be connecting a device that uses
EIA-422 serial interface (e.g., Tran-x), you should reconfigure the
port for EIA-422 before connecting any cables. Please see

Section

4.4

.

NOTE:

Most serial printers, plotters, and modems use EIA-232
serial interface and do not have RJ-45/RJ-11 modular connectors.
Adapters are required to convert from DB-25 connectors to
modular connectors. BayTech has a complete line of adapters and

PRINT SERVER INSTALLATION USING
PCONSOLE

This section addresses setting up your BayTech print server on the
network using PCONSOLE. You should have a basic knowledge of
NetWare, particularly the PCONSOLE program. If you are
unfamiliar with NetWare, you should contact a local dealer for
installation assistance. You may use PCONSOLE or the BayTech
utility software to add the BayTech print server to your network. If
you wish to use the BayTech software, please see

Section 7

.

NOTE:

If your application requires that you change any of the

BayTech print server's default parameters (see

Section 4.6

), you
must use the BayTech software utilities. The BayTech p rint server
will not read any configuration changes made in PCONSOLE (i.e.,
print server name and serial parameters). If you use PCONSOLE
to add the BayTech print server to the network and assign print
queues, a quick way to change these parameters is to use the
BCON.EXE command line utility (see

Section 7.8

).

Follow the steps below to add the BayTech print server to the
network using PCONSOLE.

1. Log in as a Supervisor and run Novell PCONSOLE.

2. Create the print server as follows:

a. Highlight

Print Server Information

followed by ENTER.

b. Press INSERT and then enter the default print server

name in the "New Print Server Name" box and press
ENTER. The print server name is added to the "Print
Servers" list.

IMPORTANT:

You must initially enter the default

print server name (see

Section 4.6

). If you wish to
change the default name, you must use the BayTech
utility software after installing the BayTech print
server (see

Section 7.8

).

34

c. Repeat this step for every BayTech print server you

wish to install. Return to the PCONSOLE main menu.

3. If the desired print queues do not exist, define the print
queues to be serviced by the BayTech print server by first
highlighting

Print Queue Information

followed by ENTER.
Next, strike the INSERT key followed by the desired queue
name. You would typically create one print queue for each
printer connected to the BayTech print server. Return to the
PCONSOLE main menu.

4. Assign the BayTech print server to service print queues as
follows:

a. Highlight "Print Server Information" from the main

menu and press <ENTER>.

b. Select the print server name entered in Step 4 from

the "Print Servers" list.

c. Select "Print Server Configuration" from the "Print

Server Information" menu.

d. Select "Printer Configuration". Define the printers for

the BayTech print server by selecting the desired
printers from the "Configured Printers" list. For each
printer, use the "Defined elsewhere" type.

e. Select "Queues Serviced by Printer" from the "Print

Server Configuration" menu.

f. Select a printer from the "Defined Printers" list.

NOTE:

"Printer 0" corresponds to Port 1 of the
BayTech print server, "Printer 1" corresponds to Port
2, "Printer 2" corresponds to Port 3, and "Printer 3"
corresponds to Port 4. Although PCONSOLE shows
printers from 0 to 15, the BayTech print server will
only recognize Printer 0 to Printer 3 for the PS-4A,
PS-4C, and PS-4E and Printer 0 for the PS-MIO.

i. Press <INSERT> at the "File

Server/Queue/Priority" box.

ii. Select a queue from the "Available Queues"

list.

iii. Enter the desired priority level 1 to 10 with 1

being the highest priority.

iv. Repeat items i through iii for each queue to be

serviced by the selected peripheral port.

v. Select any other printers on the BayTech print

server which will service print queues and
repeat items i through iv.

5. Repeat Step 4 for each BayTech print server you have
installed on the network and then exit PCONSOLE.

6. Activate the BayTech print server by applying power to it.

7. The installation is complete. You should use the BayTech
software utility if you need to change any of the BayTech
print server settings. Refer to

Section 7.8

for a detailed
explanation of the various utility commands. Otherwise, you
should be able to print through the BayTech print server
using normal NetWare print commands (e.g., CAPTURE,
NPRINT, or PCONSOLE). BayTech print server will support
all of PCONSOLE's Print Server/Control functions. Please
see

Section 8

for modem sharing instructions and

Section 9

for a definition of the LEDs on the front panel. If you
experience any difficulties, please refer to

Section 7.1

through

Section 7.6

for detailed information on PSQMGR.

Section

7.7

discusses quick installation using PSQMGR. A command line
version of PSQMGR (BCON.EXE) is provided allowing you to
perform some basic PSQMGR functions from a DOS prompt. You
may configure the BayTech print server name, serial printer port
configuration, virtual circuit connection, line delay, and update
operation mode with BCON.EXE (see

Section 7.8

).

NOTE:

If you are adding your BayTech print server to the network

using PSQMGR, proceed to

Section 7.7

(Quick BayTech Print
Server Installation Using PSQMGR) for step by step instructions. If
you have already added the unit to the network and assigned print
queues to it using PCONSOLE, you may wish to use BCON.EXE to
make any desired changes to the print server parameters.

GENERAL INFORMATION

PSQMGR is a menu-driven general print server management utility
which is also used to configure the BayTech print server. On any
BayTech print server, you may change such items as the print
server name, the parameters of serial printer ports, the queue
service interval, and the update operation mode. In addition to
programming these unique features for the BayTech print server,
PSQMGR may be used to perform the same print server
management functions as Novell PCONSOLE (i.e., install any print
server, set printer configuration, assign print queues, etc.).

PSQMGR will automatically determ ine all file servers, print servers,
and print queues on the network when it is executed and will
update such information as printer configuration and queue files on
the selected file servers. You may view this information on either a
file server or print server basis. This data may be accessed by the
PCONSOLE utility if required.

PSQMGR provides a user-friendly menu convention that will allow
you to use a mouse. PSQMGR will allow you to manipula t e up to
32 file servers simultaneously and change file servers from most of
the menus. The file servers being serviced and file servers to be
serviced appear in adjacent menus.

W hen installing a new print server, PSQMGR gives you the ability
to view all un-installed advertising print servers and will
automatically show you all file servers on which the print server
may be installed. You may selectively delete a print server on
various file servers from one menu. Also, when you delete a print
server, PSQMGR will delete the bindery item and all relevant
directories so there will be no unused directories on the file
server(s).

You may manipulate print server operator and user lists for the
same print server on multiple file servers from one menu in
PSQMGR. This is also true for print queue operator and user lists.
W ith PSQMGR, you may select a password for the print server
that will be registered simultaneously on all file servers on which
the print server is installed. When changing printer configurations,
if a printer has different configuration information on separate file
servers, PSQMGR will automatically make the necessa ry
corrections ensuring printer configuration files on all selected file
servers are consistent.

W hen assigning print queues using PSQMGR, changing file
servers will allow you to view all queues assigned to a printer port.
Queue assignment may be performed across file servers. You
may use the same queue name on different file servers.

EXECUTION, CONVENTIONS, AND
INFORMATION MENU

IMPORTANT:

The print server should be connected to the network
and powered on before using PSQMGR. You should execute
PSQMGR from a workstation with supervisory privileges to make
changes to the print server and the network. PSQMGR should be
located on a public subdirectory.

To execute PSQMGR, type

PSQMGR

from the network prompt.
An introductory menu will appear for a few seconds showing the
BayTech logo, program name, and revision number. Next, the
"Information" menu will appear as follows:

This menu is used for ident ification purposes only. The "Information"
menu will appear when you first enter into PSQMGR and when you select
the  (About) symbol in the upper left corner of your screen. Press the
<ESC> or <ENTER> keys or click on t he [] symbol in the upper left
corner of the "I nformation" menu with your mouse to close this menu.

NOTE:

In this manual, menu titles will be shown in quotes (e.g., "Menu

Title"). Menu choices will be shown in italics (e.g.,

Menu Choices

).

PSQMGR allows you to use several conventions to highlight and select
various menu items. The easiest way is to use a mouse to click on the
desired item. Individual menu items may also be selected by pressing
the

ALT

key and the letter associated with the desired it em
simultaneously. To highlight items such as file/print servers and print
queues, you may use the arrow keys if you do not have a mouse. Some
menu choices will prompt you to type in the relevant inform at ion ( e. g.,
print server name). Some m enu choices will display a drop-down menu.
You may highlight the desired item and press <ENTER> or double click
with the mouse

NOTE:

The parallel ports of the PS-4A and PS-4E are capable of sending
data to the printer at r ates in excess of 90K bytes/sec. Some older
printers may lose data at this rate due to the slow response of their busy
lines. If you notice a parallel pr int e r losing data, you may program t he
parallel port(s) on the PS- 4A or PS-4E to print slower by configur ing the
"Line Delay" option in the port conf iguration menu. Enter a number
between 0 (no delay - default) and 40 in the indicated field. The proper
setting for the printer will require som e experim entation. The lowest
setting without incurring data loss should be used. Most parallel printers

[Preferred Server ]

From the factory, the BayTe ch print server will initialize on power­up or reset by searching all file servers on the entire network for
print queues to service. Usually, this presents no problems to
network users and allows for "plug and play" operation. However,
for a large network with many file servers or for a network with a
bridge connected, this type of operation may cause print server
initialization difficulties and/or undesired login attempts on file
servers which contain no queues for the print server to service. In
this case, it may be desirable to limit the BayTech print server
access to a specified set of file servers on which to search for print
queues by using

Preferred Server Operation

.

The

[Preferred Server ]

selection in the "BayTech PrintServer
Setup" menu instructs the BayTech print server to login to a single
file server (specified by a print server operator) when the unit is
powered up or reset. The print server will read a list of other file
servers containing print queues for it to service. This list is
generated by PCONSOLE or PSQMGR. This operation is
analogous to the operation of Novell's "PSERVER". A
"FileServers" menu will appear inside the "BayTech PrintServer
Setup" menu similar to that shown on the following page:

Select the desired file server. The name of the preferred file server
will appear in the

Pref Server :

field. If you currently have a
preferred server and wish to return the print server to its network­wide initialization mode, select the

Disable Prf Svr Mode

choice in

the "File Servers" list shown above.

NOTE:

Regardless of the initialization mode selected, the print
server must be reset after all queue assignments are performed on
the file servers to allow the print server to read its queue
assignments and attach to the designated queues. You must reset
the print server manually if using manual update operation mode or
wait for the update interval to elapse if using automatic update
operation mode.

BCON.EXE COMMAND LINE UTILITY

You may review the status of a single print server or all advertising
print servers installed on the network by using the BCON.EXE
command line utility. In addition, BCON.EXE allows you to perform
some basic functions of PSQMGR for BayTech print server
models. The BCON commands are performed from a DOS
prompt. BCON commands adhere to the following format:

BCON [PRINT SERVER NAME] [PARAMETER 1] [PARAMETER 2]...

You may enter BCON commands in upper or lower case. PRINT
SERVER NAME is the name of the individual print server that you
wish to configure or check the status of. PARAMETER 1,
PARAMETER 2, ... are configurable items for the BayTech print
server which are described in the table on the following page. You
may specify as many parameters as you wish.

Each parameter in

the BCON command must be separated by at least one space.

You may receive an on-screen help menu by typing

BCON ?

. If no
parameters are specified, you will receive status information for the
print server name specified. If a print server name and parameters
are not specified, you will receive status information for all
advertising print servers.

The status information you will receive includes the print server
name, node address, version number, server type, printer status,
number of printers, queue service mode, and file servers being
serviced. For BayTech print server models, you will also receive
port configuration information which will show the service mode,
baud rate, data bits, parity, buffer size, current form, stop bits, and
handshaking for each individual peripheral port.

70

The table below provides a list of parameters supported by the
BCON command utility. These parameters apply to Print Servers

MODEM COMMUNICATION

Any authorized user may connect to and communicate with an external
modem connected to a PS-4C or PS- 4E Print Server Plus. Modem
communication includes connecting to a modem from a network
workstation and issuing modem com m ands ( e.g., dial commands). This
is referred to as " dial- out " modem communication. Modem
communication also allows a remote user to dial into a net work m odem
and gain access to the network thr ough a local "host" workstation. This
is referred to as " dial- in" m odem communication. Once a virtual
connection is established, the remote user m ay perform any operation
the local host workstation is capable of including network operations.

Print Server Plus modem comm unicat ion ut ilizes the MSHELL.EX E and
DIAL.EXE progr am s . MSHELL is a memor y resident program which
allows authorized users to connect to a network modem and do dial- out
communication using network comm unications software such as
Procomm Plus® for networks or Mirror III LAN®. MSHELL is also used
on a local "host" workstation to allow a remot e user to dial-in to the
network modem and access the network t hr ough the local host
workstation using third par t y software such as pcANYWHERE/ LAN



version 4.5. MSHELL generates various messages immediat ely after a
connect or disconnect string is issued in r esponse t o various conditions
as summarized in

Appendix B

.

DIAL is a program that allows users to select network modems from a
menu for dial-out oper at ion and assign host workstation IDs f or dial- in
operation. Print Server Plus m odem communication also utilizes the
MOPEN.EXE and MCLOSE.EXE program s . MOPEN is used to open a
virtual connection with a network modem for dial- out applications.
MOPEN is used in dial-in applications to instruct a local host workst at ion
to advertise to the Print Server Plus that it can service a remote user.
MCLOSE is used to close an existing virtual connection with a network
modem for dial-out applicat ions.

MCLOSE is used in dial-in applications
to instruct a local workstation to stop advertising that it can service a
remote user.

72

Section 8.1

discusses dial-out modem communication and

Section

8.2

discusses dial-in modem communication.



DIAL-OUT MODEM COMMUNICATION

Use the following procedure to perform Dial-out modem
communication using MSHELL.EXE:

1.

IMPORTANT:

The modem must be connected to a serial
port on the Print Server Plus with a Virtual setting of modem
(see

Section 7.6.5.1

). See

Appendix A

for the
recommended modular adapter and cable pinouts. Any user
on the network that will need to use the modem for dial-out
communication must have Virtual Access enabled (see

Section 7.6.5.5

). Your network communications program
must support EXTENDED BIOS 14 calls in order to work
with the Print Server Plus (e.g., Procomm Plus for networks
or Mirror III LAN).

2. Copy MSHELL.EXE, MOPEN.EXE, MCLOSE.EXE, and
DIAL.EXE to the subdirectory where your network
communications software is located or to a directory that is
in the PATH (e.g., F:\PUBLIC).

3. Load MSHELL.EXE by typing

MSHELL

from the

subdirectory prompt.
MSHELL will generate messages from the DOS prompt

when first loaded to inform you that it has been successfully
loaded and that it is already loaded in the event you try to
load MSHELL again.

NOTE:

You may unload MSHELL by typing

MSHELL U

from the prompt. MSHELL will generate a message to
inform you that it has been unloaded from memory. You
may obtain a readout of the available MSHELL parameters
by typing

MSHELL ?

from the appropriate prompt.

4. You must issue certain commands to the Print Server Plus
to establish a virtual connection with a network modem. You
may send the necessary commands from a DOS prompt
(Step 4a), from within your network communications
software (Step 4b), or by using the DIAL program (Step 4c).

4a. DOS Method: The DOS method to open a virtual

connection utilizes the MOPEN command which has the
following syntax:

MOPEN <print server name> <n> <t>

where <print server name> is the name given to the Print
Server Plus using PSQMGR and <n> is the port number the
modem is connected to on the Print Server Plus (0 to 3).
There should be a single space between MOPEN and <print
server name>, a space between <print server name> and
<n>, and a space between <n> and <t> (if used).

WARNING:

Do not use the exclamation point symbol (!) as
part of the print server name which is configured using
PSQMGR if you intend on using the MOPEN statement to
establish a connection with a network modem.

The optional parameter <t> causes MOPEN to enter into a
terminal mode after establishing the connection. This allows
a user to communicate with the modem without having to
execute a communications package. Anything typed on
your keyboard will be sent to the modem and any data
received by the modem will appear on your terminal screen.
Type <ESC> to terminate this mode.

If a virtual connection is established with a modem port
using the MOPEN terminal mode, you may instruct the port
to go into a loopback mode where the selected port's UART
will loop back all characters typed by the workstation.
Loopback mode is useful in troubleshooting communication
problems with the attached modem. If characters are
looped back by the selected port, this indicates the port is
functioning at the UART level.

74

Loopback mode is initiated by sending the following
command after a virtual connection is established:

---BT[LOOPBACK_ON]

. Loopback mode is terminated by

sending the following command:

---BT[LOOPBACK_OFF]

.

The virtual connection with the network modem may be
terminated from a DOS prompt by sending the

MCLOSE

command.
The DOS method to establish and terminate virtual

connections is usually implemented via batch file. For
example, you could name the batch file MODEM.BAT.
MODEM.BAT would have the following general format:

MSHELL
MOPEN <print server name> <n>
IF ERRORLEVEL 1 GOTO END
PCOMNET
MCLOSE
END

Here, we assume you are using Procomm Plus for
Networks, executing the batch file from within the Procomm
subdirectory.

4b. Network Communications Software Method: You may

establish a virtual connection from within your network
communications software by issuing the following command:

---BT[print server name(n)]

where "print server name" is
the name given to the Print Server Plus using PSQMGR and
"n" is the port number the modem is connected to on the
Print Server Plus (0 to 3).

The virtual connection may be terminated from within your
network communications software by issuing the following
command:

---BT[]

. This command must be preceded by

two seconds of inactivity.

You may send the ---BT[...] connect and disconnect strings
discussed on the previous page by manually typing them
from within your network communications software or using
macros. If using Procomm macros, you should put two tilde
symbols (~) preceding the disconnect string to implement a
two second delay.

You may initiate loopback mode as discussed on the bottom
of Page 72 by sending the following command after a virtual
connection is established:

---BT[LOOPBACK_ON]

.
Loopback mode is terminated by sending the following
command:

---BT[LOOPBACK_OFF]

.

4c. DIAL.EXE Method: The DIAL.EXE program supplied with

the Print Server Plus may be used to establish and
terminate virtual connections. To execute DIAL.EXE, type

DIAL

from the appropriate subdirectory prompt. When you
execute DIAL.EXE, an "Information" menu will appear. Type
any key to close the "Information" screen.

To select a modem for Dial-out operation, type

ALT-O

or

click on

DialOut

with a mouse. The "Modem Selection"

menu will appear similar to the following:

76

This menu displays a list of network modems in the

Network

Modems

field,

Print Server:, Modem Name:, On Port:, [

Open Modem ]

, and

[ Cancel ]

.

Print Server:

is the name of

the Print Server Plus the highlighted modem is connected to,

Modem Name:

is the name given to the modem in

PSQMGR, and

On Port:

is the Print Server Plus port number
the modem is connected to. Highlight the desired network
modem and select

[ Open Modem ]

to request a virtual
connection to that network modem. The DIAL.EXE program
will display a "Communication Window" menu while the Print
Server Plus attempts to establish a virtual connection with
the network modem. The "Communication Window" menu
displays the actual commands sent out and the response
from the Print Server Plus. When a virtual connection is
established, the "Communication Window" menu will display
the message "Remote Connection Established" as shown
on the following page. The DIAL.EXE program will be
terminated once a virtual connection is established or

Exit

is

selected.

If you execute DIAL.EXE while a virtual connection already
exists between your workstation and a network modem, a
menu similar to the following will appear:

78

Close the connection with the displayed network modem or
choose

[ Cancel ]

to leave the virtual connection intact. The
DIAL.EXE program will display the "Communication
W indow" menu while the Print Server Plus is terminating the
virtual connection with the network modem. When the
virtual connection is terminated, the "Communication
W indow" menu will display the message "Remote
Connection Terminated" as shown below.



DIAL-IN MODEM COMMUNICATION

Print Server Plus dial-in modem communication allows a remote
workstation to dial-in to a network modem and gain access to a
local workstation by using third party software such as Norton

pcANYWHERE/LAN version 4.5 or 5.0. Once a virtual connection
is established, the remote user may perform any operation the local
workstation is capable of including network operations. The steps
involved in setting up the Print Server Plus for Dial-in operation
include configuring PSQMGR (optional) and pcANYWHERE/LAN.
You must also load MSHELL.EXE on the local network
workstation(s) and instruct them to advertise to the Print Server
Plus. Finally, there is a procedure for the remote workstation to
follow when dialing in. The following steps describe these
considerations in more detail.

1.

IMPORTANT:

The modem must be connected to a serial
port on the Print Server Plus with a Virtual setting of modem
(see

Section 7.6.5.1

). See

Appendix A

for the
recommended adapter and cable pinouts. Your network
communications program must support EXTENDED BIOS
14 calls in order to work with the Print Server Plus (e.g.,
Norton pcANYWHERE/LAN version 4.5). The modem
should be programmed to use hardware flow control
(handshaking) and to have DCD follow the state of carrier.

2.

NOTE:

This step is optional depending upon whether or not

the default dial-in modem parameters in PSQMGR (

[ Modem

Setup ])

are acceptable (see

Section 4.6

).

Refer to

Section 7.6.5

in the Operator's Manual (Print

Servers - [ Config ]). In order for the

[ Modem Setup ]

selection to be highlighted, you must have supervisory
access. In addition, the Print Server Plus must be in the
Preferred Server mode as described in

Section 7.6.7.4

and
you must be logged into the preferred file server. If you
select

[ Modem Setup ]

, you will receive the following menu:

80

This menu shows

Modem Init String:, Prompt String:

,

Answer String:, HangUp String:, WkStn Init String:, Access
Code:, Time Out:

, and

Nmbr of Rings:

. The values shown
here are default values. If the default values are acceptable,
you may proceed to Step 3. The following items describe
these selections in more detail.

NOTE:

The

[ Factory Setup ]

selection will reset all strings
and other fields to the factory default values which are given
in the following items. The factory default values should be
satisfactory for most applications.

2a. The

Modem Init String

is sent to the local network modem
when the modem is initialized after a call or when the Print
Server Plus is reset. The def ault

Modem Init String

is

ATS0=1&C1^M (^M =

Carriage Return

) which will put a
Hayes compatible modem into auto answer mode and
force DCD to f ollow the state of carrier detect. You may
program the

Modem Init String

to be any character string

up to 46 characters

.

NOTE:

If you configure the

Nmbr of Rings

to be a

non-zero value (see Step 2h), the

Modem Init String

should not be a command to put the modem into auto
answer mode and a valid answer string should be
entered in the

Answer String

field (see Step 2c

below). Conversely, if the

Modem Init String

is a
command to put the modem into auto answer mode,
the

Nmbr of Rings

should be 0 and no answer string

should be specified.

2b. The

Prompt String

is sent to the remote workstation
when the modems connect. This string prompts the
remote user to enter the name of the desired local
network workstation ID. The remote user has up to
60 seconds to enter this ID. The workstation IDs for
the various network users are programmed using the
DIAL.EXE program as described in Step 4. The
default

Prompt String

is

^M^JEnter Workstation ID

(Ctrl-C to Hangup):

, where ^M is

Carriage Return

and

^J is

Line Feed

. You may program the

Prompt String

to be any character string up to 46 characters.

NOTE:

If the

Access Code

is enabled, the

Prompt

String

will be sent only after the

Access Code

has

been entered correctly (see Step 2f).

2c. The

Answer String

is sent to the local network
modem when a call comes in. This string is sent after
the number of rings interval has elapsed and is
usually an answer command in the event the modem
is not in the auto answer mode. The default

Answer

String

is blank because the default modem mode is

auto answer. You may program the

Answer String

to

be any character string up to 22 characters.

82

2d. The

Hang Up String

is sent to the local network
modem upon loss of carrier. In addition to sending
the

Hang Up String

, the Print Server Plus will toggle
the modem port's DTR line from high to low for 0.5
seconds as a redundant measure to inform the local
modem to hang up. The default hang up string is

~~~+++~~~ATH0^M

where ~ is a 0.5 second delay

and ^M is

Carriage Return

. You may program the
HangUp String to be any character string up to 22
characters. You may use as many delay characters
as necessary for your particular modem configuration.

2e. The

WkStn Init String

is sent to the local network
workstation when a virtual connection is made. The
default

WkStn Init String

is disabled (blank). You may

program the

WkStn Init String

to be any character

string up to 22 characters.

2f. The

Access Code

is similar to a password. If the

Access Code

is enabled, the remote user will receive

the prompt "Enter Access Code" prior to the

Prompt

String

described in Step 2b. The remote user must

first type the

Access Code

followed by the local
W orkstation ID to get a virtual connection with the
local network workstation. You may use the wildcard
characters * or ? in the

Access Code

where * allows
multiple "don't care" characters and ? a single "don't
care" character. For example, if you program the

Access Code

to be BAY*^M, the remote user would
have to type "BAY" followed by any number of other
characters and

Carriage Return

. The default

Access

Code

is disabled (blank). You may program the

Access Code

to be any character string up to 14
characters.

2g. The

Time Out

interval is used by the Print Server Plus
to instruct the local network workstation to reinitialize
advertising after the modem connection has been
terminated. If a remote workstation has a connection
with a local host workstation and the modem
connection is disrupted or terminated, the remote
user may re-establish the modem connection and
resume the session with the local host workstation
before the

Time Out

interval elapses. The default

Time Out

interval is 90 seconds and may be
programmed from 0 to 650 seconds. If you program
the

Time Out

interval to be 0 seconds, the Print
Server Plus will immediately instruct the local host
workstation to reinitialize after the modem connection
has been terminated.

2h. The

Nmbr of Rings

is the actual number of rings the

Print Server Plus will wait before sending out the

Answer String

described in Step 2c. The default

Nmbr of Rings

is 0. You may program the

Nmbr of

Rings

from 0 to 99 rings. Use this option if your

modem is not in the auto answer mode.

3. pcANYWHERE/LAN Host Setup: Here we assume that
you have some knowledge of Norton pcANYWHERE/LAN.
We will limit the discussion to those consid erations that
pertain to dial-in modem applications using the Print Server
Plus. Use the following procedure:

3a. Load pcANYWHERE/LAN by typing

AWLAN

from the

appropriate prompt. Select

Hardware Configurations

from the Main Menu.

3b. Type <INS> to add a new configuration. Enter the

desired identifying name up to 30 characters followed
by <ENTER>. A "Configur ation: XXX" menu will
appear where XXX is the desired identifying name.
This menu shows several fields. You will need to

84

change certain fields to have specific values. The

Device/Port:

field should be "Int14". The

Modem:

field should be "None". The

Connection started by:

field should be "Carrier Detect". The

Connection

ended by:

should be "Carrier Detect". You may

program the

Data rate:

field to be any value other
than "Max" or "115200". The typical value for this
field is "9600". The data rate selected has no effect
on the speed of communications but must be set in
order to maintain compatibility with BIOS.

3c. Type <ESC> and a prompt will appear asking you if

you wish to save the changes permanently. Type "Y"
in response to this prompt.

4. Assigning a Workstation ID: One or more local workstations
must be assigned a Workstation ID in order to perform dial­in communication. The Workstation ID is a character string
that a remote user must enter in response to the Prompt
String (see Step 2b) in order to establish a virtual connection
with the local workstation. The Workstation ID may be
programmed to be any character string up to 46 characters.
The following characters are not valid: a space ( ), forward
slash (/), semicolon (;), colon (:), plus symbol (+), minus
symbol (-), back slash (\), asterisk (*), and comma (,). The
workstation ID may be programmed from a DOS prompt
(Step 4a), from within your network communication software
(Step 4b), or by using the DIAL.EXE program (Step 4c).

IMPORTANT:

You must load the MSHELL program before
assigning a Workstation ID to a local workstation (see Page
71, Steps 2 and 3).

NOTE:

There is no way to permanently assign a Workstation ID
to a local workstation. The Workstation ID must be assigned
every time a workstation is to be used for dial- in applicat ions ( e. g.,
after boot-up or after the workstation has been inst ructed to stop
advertising as discussed in Step 5).

4a. DOS Method: You may assign a local workstat ion a Workstation

ID from a DOS prompt using the MOPEN command which has the
following syntax:

MOPEN Workstation ID

.

NOTE:

The actual time this comm and needs t o be sent depends
upon your application. For example, if t he local work station is
programmed to r eboot every time a connect ion is t er m inat ed by a
remote user, you would probably want to include this command in
the AUTOEXEC.BAT file of the local workstation. If you want the
local workstation to advertise aft er business hours only, you may
wish to manually send this command from a DOS pr om pt before
leaving the office.

4b. Network Communicat ion Software Method: You may assign a

local workstation a Workstation I D from within your network
communications package by typing

---BT[Workstation ID]

manually from within the packag e or by using m acros.

4c. DIAL.EXE Method: The BayTech DI AL. EXE utility program ma y

be used to assign a local workstation a Work st at ion ID. To invoke
the DIAL.EXE prog r a m , first make sur e t hat MSHELL is loaded.
Next, type

DIAL

from the appropr iat e subdir ectory prompt.

The DIAL.EXE prog r am will respond with an "Information" screen
when executed. Type any key to close this screen. Select

Dial-in

with a mouse or type

ALT-I

. The "Enter Work Station ID" menu

will appear as shown on the following page:

86

Enter the desired ID in the

Work Station ID :

field. A remote
user must type in the name entered here in order to connect
to this workstation once a connection is made. Select

[ OK ]

after the desired workstation ID has been entered. This
action will terminate the DIAL.EXE program.

5. W orkstation Advertising: A workstation on the network must
advertise to the Print Server Plus that it is available for Dial­in operation. If a remote user dials in to a network modem
and enters a non-advertising Workstation ID, the remote
user will be sent an error message. The loca l workstat ion
will automatically advertise after the Worksta tion ID has
been assigned (see Step 4).

6. Once you have made the necessary configuration changes
in PSQMGR and pcANYWHERE/LAN, and the local
workstation is advertising, you are ready to perform Dial-in
operations. The MSHELL program should be loaded on the
appropriate local host workstation(s). Use the following
procedure:

6a. Set up the local host workstation(s) as follows: Run

pcANYWHERE/LAN, select "Host Operations", select
"Active Configuration" (i.e., Dial-in, Int14), select
"Begin Host Operations", select "Exit, Allow Incoming
Calls", or "Wait for Connection".

NOTE:

It is suggested that the host workstation be
logged out of the network while awaiting a call for
security reasons. A remote user would typically log-in
when a virtual connection is established with the local
host workstation.

6b. A remote user initiates the dial-in connection by first

loading pcANYWHERE/LAN on the remote
workstation. Perform a normal modem dial command
to dial to the network modem. If using leased phone
lines, the modems should connect once both are
powered on.

6c. Once a modem connection is made, an access code

will appear if enabled in PSQMGR. If so, type the
required access code (see Step 2f). Once the correct
access code has been entered or if

Access Code

is

disabled, the

Prompt String

will be sent to the remote
workstation (default is ^M^JEnter Workstation ID (Ctrl­C to Hangup):). Type the appropriate workstation ID.
This will be the same workstation ID as that
described in Step 4. The remote user has up to 60
seconds to enter the workstation ID once the prompt
string appears. The local host workstation will then
automatically go into pcANYWHERE/LAN. Both
workstations will remain connected until the
connection is terminated.

88

NOTE:

You may program pcANYWHERE/LAN to

enable the

caller information list

which would prompt
incoming callers to enter a password and then screen
the password for security clearance before
continuing. Please see your pcANYWHERE/LAN
documentation for more information.

6d. To terminate the connection, the remote user typically

instructs the remote modem to hangup. Once carrier
is lost, a timer on the Print Se rver Plus will initiate.
Once the timeout interval has elapsed (see Step 2g),
the Print Server Plus will terminate the virtual
connection with the workstation.

NOTE:

If carrier is lost accidently, the virtual
connection to the host workstation will remain intact
during the timeout interval. The remote user may re­establish a connection with the host workstation and
pick up where they left off if a connection is made
before the timeout interval has expired. If multiple
remote users are expected to dial-in, the timeout may
be set to zero to prevent a second caller from
obtaining the first caller's connection.

IMPORTANT:

It is highly recommended that the modem's DCD
line be programmed to follow the status of carrier. However, if the
network modem's DCD line is forced high due to a modem setting
or a cabling error, a re mote user will have to type

Control-C

to get
the access code and/or prompt string described in step 6c on the
previous page. The remote user will have up to 60 seconds to type
in the appropriate access code and/or workstation ID. If a valid
workstation ID has not been sent within 60 seconds, the Print
Server Plus will resend the prompt string and re-enable the port for
dial-out operation.

LED INDICATORS

The PS4A, PS-4C, and PS-4E models have six LED indicators on
the front panel: a green power LED, a red network activity LED,
and four red peripheral port activity LEDs. The

POWER

LED will

illuminate when the unit has power applied to it. The

RX/TX

LED
will illuminate when the unit detects activity on the network. When
the unit receives a print job to send to a printer or a network user
has a connection to a modem, the LED for the target peripheral will
illuminate (1, 2, 3, or 4).

The PS-MIO has one network activity LED which will illuminate
whenever activity is detected on the network.

All 10BASE-T models have a

LINK

LED on the back panel which
will illuminate if there is a good connection between the BayTech
print server and the hub.
