1.1 Introduction to the IntelligentSerialInterface

The new IntelligentSerialInterface card, the MultiModemISI, is a
hardware solution for adding fast serial ports to communication
servers and async hosts that have 16-bit ISA-bus architecture. Serial
ports are essential to communication servers, which pool modems
and other communication devices for users on a LAN, and to
asynchronous hosts that provide user access through serial ports.
The MultiModemISI integrates ISI mutiport and
modem technology on a single board. It is a "full sized" add-on card
which supports a high-speed interface up to 115.2K bps per port.
This card has multiple
bps) fax modems providing high speed buffering for multiple serial
ports.

This manual contains product specification, installation instructions,
and technical support information which will assist you in the
installation process. It is assumed that you have basic PC skills at
the very least. Therefore, we have not included step-by-step
instructions for such basic operations as logging in and file editing,
etc.

1.2 Product Description

The MultiModemISI is ideally suited to use in PC networks
environments because it provides an integrated hardware solution
for remote access for both Windows NT and Novell-based LANs. In
particular, to ensure smooth Novell network integration, the
MultiModemISI ships with a NetWare Loadable Module for NetWare
ConnectTM communication servers that enable it to support state-of­the-art features such as remote dialing and modem pooling. And,
the MultiModemISI easily integrates into the Windows NT platform
since it fully supports Microsoft's Remote Access Server software.
This allows it to comfortably operate with popular network protocols
such as TCP/IP and NetBIOS. The MultiModemISI ships with drivers
for other multiuser operating systems such as SCO® UNIX®, SCO
XenixTM, and SCO UNIXWare®.

The MultiModemISI includes an Intel 16 MHz 80186 proccesor and
256K of RAM that work dynamically to allocate resources to the
most active modems.

Chapter 1 - Introduction and Description

Simple to install, the MultiModemISI can be used to add multiport,

as easily as plugging in an expansion card, running the driver
software, and connecting the phone lines.

Network managers have the option of starting with the base four
modem configuration (model #ISI334/4), and then adding four more
modems at a later date without having to use another PC expansion
slot.

This is accomplished by pairing one MultiModemISI with an auxiliary
module (model #ISI3334/EC) interfacing both with on-board
connectors.

Some MultiModemISI on-board components include one jumper
block for activating the number of ports in increments of 4 or 8. One
bank of 8 DIP-Switches for I/O address selection and one IRQ
jumper block, that control both the MultiModemISI and auxiliary
module I/O addressing and IRQ values.

When installing a single MultiModemISI in your PC, the installation
scripts create 8 devices. The first 4 devices are active, however, the
4 devices on the auxiliary module are not active until connected to
the MultiModemISI.

3) Installing the card into the PC.

Chapter 2 - Hardware Installation

2.3 Determining Current System Settings

When you install a device into your computer, the processor must
have a means of routing information to and from the device and the
device must have a means of gaining the processor's attention.
These are called Input/Output (
Requests
I/O addresses and one IRQ value which are not used by any other
device in your system. When selecting a unique base I/O address,
be sure that the next address is also unused. To determine your
MultiModemISI's current settings, refer to Appendix A and B.

If you are certain that these settings are not already in use, continue
with the hardware configuration and installation. You can install up to
four MultiModemISI cards into your system. Each card is shipped
with its IRQ set at level 10 and a base I/O address of 210 hex.
Check your system’s device settings to see if these values can be
used. If the defaults are already in use, select a unique IRQ and I/O
address and record those values for the hardware and software
installation sections that follow.

Note: If you choose IRQ 3 or 4, you may have to disable a COM
device from your BIOS setup. Also, most 386 or higher compatible
computers will not be able to assign IRQ2 to the MultiModemISI card
because IRQ2 is used for slave interrupt control.

for the use of Multi_View Utility. (1-256):

Note: at this prompt, you must enter a minimum of 8 for each
board installed (i.e., 8 for one card, 16 for two cards, etc.)

Enter the proper value and press <Enter>.

6 The /dev directory holds device-information files used by the

kernel to access the hardware. When you add an ISI, you must
give the ISI ports unique names, so they do not conflict with
existing ports or other devices known to your system. If you use
an existing device name to identify your new ISI ports, the
existing device is “deleted” when the ISI port using its name is
created.

3.6 Activating Ports in SCO Open Server 5

SCO Open Server 5 provides a device database which monitors the
activity of serial ports through which users can log onto the host. If
your ISI ports are used by terminals (i.e., to allow users to log onto
your host), you must create an entry in the system's device
database, which furnishes specific information for the terminals that
will be used on each ISI port. The database is referenced each time
a user attempts to login. If there is no database entry for a particular
terminal, access to the host is denied.

Table 3-5
Creating Device Entries with SCO's sysadmsh

Step Procedure

1 Power up your system and take note that the firmware for each

ISI gets loaded successfully. If the firmware for a given ISI card
does not get loaded, none of its ports will be accessible (should
this happen, see the Multi-Tech's Administrative Utility section in
this chapter).

2 The device database can be modified in two ways. To create

terminal accounts with default settings, type /tcb/bin/
ttys_update. To customize the terminal entries, you must create
them individually by entering the system administrator's shell
(which means you must be logged in as the root user). You can
enter the administrator's shell by typing: sysadmsh press
<Enter>

3 You can create device entries for each port of your ISI card(s) by

selecting the following options from the database menu:

Accounts | Terminal | Create

4 Enter the complete name of the first device you want to create,

substituting the base name, board number and port letter for the
parameters: ttylbx. (Use a lower case x value for local DTE-­terminal--support, an upper case X value for modem control for
each port you want to enable). The port status can be altered
later; however, one setting must be selected at this time.

33

ISI3334/4 Hardware/Driver Installation Manual

Table 3-5 (cont'd)
Step Procedure

5 Repeat this process for each port on each board you have

installed. Record the settings you select for each port.

6 Using the device names created in the previous section, type the

following command for each port you wish to activate at this
time:

enable

7 Repeat this command for each port you wish to activate, using

the lower case letter for local terminal usage or upper case for
modem control.

Note: Only one of the options (i.e., modem control or local
terminal access) should be enabled for any port at one time. For
example, you cannot enable ttyl1a and then enable ttyl1A. To
change the status of a port, disable the current status (disable
ttyl1a) and then enable it for the desired status (enable ttyl1A).

ttylbx

3.6.1 Removing the Driver (SCO Open Server 5)

If you find it necessary to remove the Multi-Tech Serial Card Driver,
you should enter the configuration utility (i.e., custom for SCO Open
Server 5) and follow the instructions to remove the entire driver and
to rebuild the kernel without the ISI driver. If it is necessary to re­install the driver, due to I/O address or IRQ overlap, you must
remove the driver first.

34

3.7 Multi_Setup Utility

This section guides you through the Multi-Tech Setup Utility for SCO
Open Server 5.0 systems. The Multi_Setup utility lets you set
various parameters for Multi-Tech's ISI card ports; such as,
transparent printing options, high baud settings (above 38400 bps),
and hardware flow control. All the changes made by the Multi_Setup
utility are in effect until the system is rebooted or until the option is
changed using Multi_Setup.

Multi_Setup has a database of “on” and “off” strings for the
transparent printing option through commonly-used terminal
emulations. If terminal type in use is not recognized by Multi_Setup,
Multi_Setup checks the
escape sequences for transparent printing through that terminal
type.

Multi_Setup options are provided in Table 3-7.

-c cps Specifies the printer speed in characters per
second. Default value of 100 cps.

-b bufsize Specifies the buffer size for transparent
printing. Valid range is any integer greater
than 0, as specified by your printer. The
default value is 250 characters.

-T term Sets the transparent printing escape
sequences to that of the terminal specified
by term. This parameter has access to the
look-up table in the terminal database built
into Multi_Setup. If the terminal is not
recognized by Multi_Setup, then the
termcap database is used to find the On and
Off escape sequences for transparent
printing.

3.8 Multi_View Utility Installation

This section guides you through the Multi_View Utility for SCO and
UNIXWare systems. During the installation of the ISI4608 drivers,
you will also install the Multi_View utility for multiple-page terminals.
This section profiles the Multi_View utility and gives you the
necessary information to create a Multi_View information file.

Once installed, Multi_View can be invoked by typing the following
command:

Multi_View [ options]

The Multi_View initializes the multiple-page capability of terminals
with multiple pages of memory. While Multi_View works even on a
dumb terminal (without multiple pages of memory), your terminal(s)
should have multiple pages of memory and be capable of retaining
the position of the cursor on each page to get the proper effect.

Most state-of-the-art terminals have multiple pages of memory,
which allow them to switch between sessions. Each page of
memory available on the terminal allows its user to establish another
session on the host. The multiscreen capability of the terminal
stores the screen information and the cursor position for each
session to a different page of memory.

Multi_View allows the host to process the session-switching hot keys
and issue the necessary escape sequence to the terminal so that the
appropriate page is displayed on screen. Multi_View treats each
new screen opened by the user as a virtual screen and maintains
mapping between each virtual screen created and a page of memory
on the terminal. The number of virtual screens and pages of memory
available are dependent on the terminal emulation, the particular
terminal being used, and the number of pseudo devices created by
the system administrator during installation.

In an ideal case, there can be as many virtual screens as there are
pages of memory on the terminal. If there are more virtual screens
specified than there are pages of memory, then two virtual screens
may be mapped to a single page of memory, in which case, both
sessions’ screens are displayed when that page of memory is
recalled.

37

ISI3334/4 Hardware/Driver Installation Manual

Once Multi_View is successfully able to read the terminal description
and initialize the terminal, it comes up with a message displaying the
hot-key sequence for “help”.

The following hot keys are defined:

• Go to nth virtual screen

• Create new virtual screen

• Switch between current and previous screens

• Provides help on hot keys

• Quits Multi_View with an exit status of zero

• Ends Multi_View with a non-zero exit status

To define your own terminal capability database, refer to the
Description File Format section below.

The following options are defined:

Options Description

-h Prints the help file. Multi_View uses the

environment variable MTDSPLY to choose
the utility to display this file. If no such
variable is found in the environment, then
Multi_View uses the “pg” utility.

38

-t This option is used to inform Multi_View to

use a terminal description that is different
from the one specified by the TERM variable
in the user environment.

-f This option lets the user instruct Multi_View
to read the terminal descriptions from a
different file than the default description file.
The default description file is “

msfile

”.

usr/bin/

Chapter 3 - MultiModemISI Driver Installation

3.8.1 Description File Format

A description file may contain descriptions for multiple terminal
types. Each terminal entry should be separated by a blank line. The
first line for each terminal contains the various names by which that
terminal is known. There are three types of entries for each terminal
emulation: 1) hot key entries, 2) terminal escape sequences, and 3)
timing specifications.

3.8.2 Hot Key Entries

These entries have three columns. The first column specifies a
mnemonic. Each mnemonic is associated with a specific action
taken by Multi_View. The mnemonics are as follows:

Mnemonic Description
vs Identified the virtual screen entry. An entry

will be present for each virtual screen that
needs to be opened by Multi_View.

sw Identifies the hot key sequence for switching

between two virtual screens.

cm Identifies the hot key sequence that

instructs Multi_View to create a new virtual
screen.

lm Identifies the hot key sequence for

displaying help on the hot keys.

qm Identifies the hot key sequence to exit

Multi_View with a zero exit status.

em Identifies the hot key sequence to exit

Multi_View with a non-zero exit status.

The second column contains the keystroke sequence that needs to
be pressed to make the action described by the mnemonic in the
first column to take place.

The third column specifies the escape sequence sent by the terminal
to Multi_View when the key combination specified in column two is
pressed.

39

ISI3334/4 Hardware/Driver Installation Manual

In other words, these entries tell Multi_View that the terminal sends
the escape sequence specified in column three to Multi_View when
the keystrokes specified in column two are pressed and that
Multi_View should take the action specified in column one whenever
it receives the characters specified in column three.

3.8.3 Terminal Escape Sequences

The terminal escape sequence entries describe the escape
sequence that needs to be sent to the terminal. The first column
contains a mnemonic. The mnemonics are described below:

Mnemonic Description
ps Describes the escape sequence that needs

to be sent to the terminal to switch to the
appropriate physical page. The physical
pages are numbered in the order they are
specified in the description file.

clear Specifies the escape sequence to clear the

screen.

The second column has the character sequence that needs to be
sent to the terminal by Multi_View.

40

3.8.4 Timing Specification

The timing specification is the interval in tenths of a second that the
utility waits before checking for an escape sequence. The timing
specification is defined below:

Mnemonic Description
time Specifies the interval, in units of 0.1

seconds, Multi_View will wait while reading
characters before checking for escape
sequences.

Chapter 3 - MultiModemISI Driver Installation

A sample file for the Wyse50 terminal is provided in the following
example:

wy50 wyse50 w50 ; line 1

vs Shift_F1 \001' \015 ; line 2
vs Shift_F2 \001a\015 ; line 3
sw Shift_F3 \001b\015 ; line 4
cm Shift_F4 \001c\015 ; line 5
cm Shift_F5 \001d\015 ; line 6
lm Shift_F6 \001e\015 ; line 7
qm Shift_F7 \001f\015 ; line 8
ps \033w0 ; line 9
ps \033w1 ; line 10
clear \033+ ; line 11
time 1 ; line 12

Line 1 Gives all the different names that the Wyse50 terminal is

known.

Line 2 Specifies the virtual screen 0 settings. When the help

screen is displayed, <Shift>+<F1> is displayed for the
virtual screen 0. The entry means that the terminal is
going to send a string with the first ASCII character
being start of header (01 Hex), second character a
hyphen (-), and the last character a carriage return
<CR> when <Shift>+<F1> is entered on the terminal
and that Multi_View is switched to the shell/process

associated with virtual screen 0.
Line 3 Specifies the entry for virtual screen 1.
Lines 4-8 Describes the hot keys to switch between the current

and previous virtual screens, create a new virtual

screen, display the help on the hot keys, quit Multi_View

with a zero exit status and end Multi_View with a non-

zero status respectively.
Lines 9,10 Describes the physical pages on the terminal. The

second string on each line gives the escape sequence

that needs to be sent out to the terminal to switch to the

appropriate physical page.
Line 11 Clear string to clear the screen.
Line 12 Specifies at least a 0.1 second wait in reading data

before going ahead and check for hot keys.

41

ISI3334/4 Hardware/Driver Installation Manual

Each character in the escape sequence or hot key can be specified
as an ASCII character if it is printable. If not printable, then it should
be specified in an octal format with leading 0's, if needed, and
preceded by a “\”. For example, an ASCII escape character can be
specified as “\033”.

Do not switch the screen while outputting as it may break the escape
sequence sent to the terminal. When there is more than one virtual
screen, all outputs from the inactive virtual screens will be blocked.
The virtual screen the user is currently working on is the only active
screen.

The fullest potential of Multi_View is realized on a multiscreen
terminal; however, Multi_View can be used on a dumb terminal that
has only a single page of memory. When there is only one page, the
screen output is unavoidably garbled from different virtual screen
outputs.

Some important ASCII unprintable characters and their octal values
are listed below.

SOH (^a) \001 STX (^b) \002
ETX (^c) \003 EOT (^d) \004
ENQ (^e) \005 ACK (^f) \006
ESC (^[) \033 Newline (NL) \012
Carriage
Return (CR) \015

42

Some known limitations are presented in the following listing:

• No null characters are allowed in the hot keys.

• No hot key can be a complete substring of another hot key.

Appendix A - Base I/O Address Switch Settings

The table below provides the DIP-Switch settings for valid base I/O
addresses of the ISI4608. The switches can be set to "OPEN" (O in
the table below) or to "CLOSED" (C in the table below). Holding the
board with the switch facing you (reading numbers 1-8 left to right),
the "UP" position for the switch is OPEN, and the "DOWN" position
is CLOSED. "S1" below is labeled as "1" on the left side of the
switch and so on, through S8. For an example, turn to page B-2 and
compare the default switch settings with the address 200h listing.

Appendix B - ISI Testing Utilities

This disk contains two files that are to be used in conjunction with ISI
boards. These files are described in two sections: 1) Operation with
factory default settings, and 2) Operation with other than the factory
default settings. These files are:

ISI3334.BIN
3334TERM.EXE

Note: This program is a DOS utility.

1. OPERATION WITH FACTORY DEFAULT SETTINGS

The 3334TERM.EXE program is a utility program that emulates a
terminal to test the connection from PC keyboard to ISI board to
Modem to ISI board to PC display. Prior to executing 3334TERM the
program must be executed to initialize the ISI board (when the ISI
board’s factory settings are unchanged).

The following screen is displayed:

ISI3334/4 Hardware/Driver Installation Manual

The first step in this utility is to identify the port to be tested. In order
for the test to function, the selected port must be connected to an
activated modem. The valid entries for the ISI are 1 through 8.
Once a port is selected, the following is displayed:

Enter 8 = 1200 baud
Enter 11 = 2400 baud
Enter 15 = 9600 baud
Enter 16 = 19200 baud
Enter 17 = 38400 baud
Enter 18 = 57600 baud
Enter 19 = 115200 baud

Enter the baud rate you wish to run ?

This step allows selection of a baud rate for testing. Once a baud
rate is selected, the following is displayed:

ISI Terminal Utility is ready. Press F10 to Exit.

This message indicates that keyboard entry can now be performed;
any characters typed on the keyboard will be sent through the ISI
board to the modem and then returned to be displayed on the PC’s
screen. When operation has been verified the utility can be exited by
pressing the F10 key.

2. OPERATION WITH SETTINGS OTHER THAN FACTORY

DEFAULTS

The 3334TERM.EXE program is a utility program that emulates a
terminal to test the connection from PC keyboard to ISI board to
Modem to ISI board to PC display. Prior to executing 3334TERM,
the program must be executed to initialize the ISI board.

Enter 3334TERM -h <CR> to display the 3334TERM program
requirements. The following screen is displayed:

A:\>3334TERM -h
Usage is:
IsIterm-I<2 to 7, 10 to 12 and 15> for specifying IRQ

level.

-A<address> for specifying base address.

-H this help screen.

Note: This program must be run anytime the PC has been powered
down or rebooted.

Appendix B - ISI Testing Utilities

Whenever the Base IO Address and/or the IRQ values have been
changed, a parameter string must be added to the command line.
The string takes the form of [-Axxxx], where xxxx represents the new
Base IO Address value and [-Iy], where y represents the IRQ value
selected. Three potential combinations exist for the formatting of the
command line:

1) Changing only the Base IO Address setting the

command line takes the form:

3334TERM [-Axxxx]

2) Changing only the IRQ setting the command line takes

the form:

3334TERM [-Iy]

3) Changing both the Base IO Address and the IRQ settings

the command line takes the form:

3334TERM [-Axxxx] [-Iy]

For example, if the Base IO Address switch setting were changed to
2C0h, then the new command line would be:

A:\>3334TERM -A2C0

The following screen is displayed:

A:\>3334TERM -A2C0
