1. Introduction

The DSP-100 provides two independent RS-232 asynchronous serial communications
interfaces for systems equipped with PCMCIA Type II and/or Type III expansion
sockets. The DSP-100 is a PCMCIA Type II (5 mm) card and is PCMCIA PC Card
Standard Specification 2.1 compliant.

The DSP-100's serial ports are implemented using 16C550 Universal Asynchronous
Receiver/Transmitters (UARTs) which are the recommended communications interface
for multitasking environments and with applications involving high data transfer rates.

The DSP-100's two serial ports are addressable in two modes:

1. 'Block Mode': The two serial ports are configured in one 16-byte continuous

block of I/O address space. The block must begin on an even 16-byte

division. Both serial ports share one IRQ level.

2. 'COM Mode': The two serial ports are configured at the standard COM port

I/O address locations. The ports may be configured as COM1 and COM3;

also, the ports may be configured as COM2 and COM4. Both serial ports

share one IRQ level.

A special interrupt status register is also available to simplify the software required to
service multiple serial ports in an interrupt driven environments. See the Hardware
Information section for details.

Two configuration software programs are provided with the DSP-100: a Client Driver,
DSP100CL.SYS, and a card Enabler, DSP100EN.EXE. Both of these programs are
executed from DOS (before entering Windows) and allow operation of the DSP-100 in
both the DOS and Windows 3.x environments. For optimal operation, however, the
Client Driver is the preferred method of installation and configuration. The table below
highlights the differences between these programs.

Card and Socket Services software is commercially available from several vendors for
most desktop and laptop PCs. If you are unsure whether Card and Socket Services
software is currently installed on your system, install the DSP-100 Client Driver as
discussed in following section. When loaded, the Client Driver will display an error
message if Card and Socket Services software is not detected.

DSP-100 User's Manual 3

2.1 DSP-100 Client Driver for DOS

Socket Services software is available from

Quatech

Inc.

In order to use the DSP-100 Client Driver, the system must be configured with Card and
Socket Services software. Card and Socket Services software is not provided with the
DSP-100 but is available from Quatech.

IMPORTANT:

Some versions of Card and Socket Services dated before
1993 do not support general purpose I/O cards. If after
careful installation of the Client Driver the DSP-100 does
not configure or operate properly, an updated version of
Card and Socket Services may be required. Card and

2.1.1 Client Driver Installation

The following procedure is used to install the DSP-100 Client Driver:

1. Copy the file DSP100CL.SYS from the DSP-100 distribution diskette onto the
system's hard drive.

2. Using an ASCII text editor, open the system's CONFIG.SYS file located in the
root directory of the boot drive.

3. Locate the line(s) in the CONFIG.SYS file where the Card and Socket Services
software is installed.

4. AFTER the line(s) installing the Card and Socket Services software, add the
following line to the CONFIG.SYS file: DEVICE =
drive:\path\DSP100CL.SYS options where options are the
DSP-100 Client Driver command line options discussed on the following
pages.

5. Save the CONFIG.SYS file and exit the text editor.

6. Insert the DSP-100 into one of the system's PCMCIA slots.
NOTE: Since the DSP-100 Client Driver supports "Hot Swapping", it is not

necessary to have the DSP-100 installed when booting the system. By inserting
the card before booting, however, the Client Driver will report the adapter
configuration during the boot process thereby verifying the changes made to the
CONFIG.SYS.

DSP-100 User's Manual 4

7. Reboot the system and note the message displayed when the DSP-100 Client
Driver is loaded. If the Client Driver reports an "invalid command line
option", correct the entry in the CONFIG.SYS file and reboot the system
again. If the Client Driver reports "Card and Socket Services not found", a
version of Card and Socket Services must be installed on the system or the
DSP-100 Enabler program must be used to configure the adapter. If the
Client Driver reports the desired adapter configuration, the installation
process is complete and the DSP-100 may be removed and / or inserted from
the system as desired. On each insertion into the PCMCIA socket, the
DSP-100 will be automatically reconfigured according to the command line
options.

2.1.2 Command Line Options

The DSP-100 Client Driver accepts up to eight command line arguments from the user
to determine the configuration of the DSP-100. If any arguments are provided, the
Client Driver will attempt to configure any DSP-100s with the options specified in the
order they are entered on the command line. Each argument must be enclosed in
parenthesis and must be separated from other arguments by a space on the command
line. Within each argument, any or all of the following parameters may be specified
using a comma (no spaces) to separate each parameter:

Baddress specifies a “block mode” base I/O address of the DSP-100 in hexadecimal.

This address must reside on an even 16-byte (10H) boundary. This option
must be omitted if using the Dmode option. If both the Dmode and
Baddress options are omitted, a “block mode” base address will be assigned
by Card and Socket Services.

Dmode specifies a “COM” mode” base I/O address configuration for the DSP-100.

The D1 option configures the DSP-100 at COM1/COM3 (3F8 / 3E8), and the

D2 option configures the DSP-100 at COM2/COM4 (2F8 / 2E8). This option
must be omitted if using the Baddress option. If both the Dmode and

Baddress options are omitted, a “block mode” base address will be assigned
by Card and Socket Services.

Iirq specifies the interrupt level (IRQ) of the DSP-100 in decimal. irq must be

one of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is
desired. If this option is omitted, an interrupt level will be assigned by Card
and Socket Services.

Ssocket specifies which PCMCIA socket the DSP-100 must be inserted into for this

configuration argument to be used. socket must be in the range 0 - 15. If this
option is omitted, the configuration argument will apply to DSP-100s
inserted into any socket.

DSP-100 User's Manual 5

U instructs the Client Driver to disable the DSP-100's interrupt status register

and enable the Scratchpad registers of the individual UARTs. This option is
only required in very rare cases where an application program requires
access to the UART's Scratchpad register. If this option is omitted, the
DSP-100's interrupt status register is enabled and the UARTs' Scratchpad
registers are disabled.

2.1.2.1 Example 1

DEVICE = C:\DSP-100\DSP100CL.SYS

In example 1, no command line arguments are specified. The Client Driver will
configure a DSP-100 inserted into any socket in “block mode” with a base address and
IRQ assigned by Card and Socket Services. The DSP-100's interrupt status register will
be enabled.

2.1.2.2 Example 2

DEVICE = C:\DSP-100\DSP100CL.SYS (d1)

In example 2, a single command line argument is provided. The Client Driver will
attempt to configure a DSP-100 inserted into any socket in “COM mode” at
COM1/COM3 and an IRQ assigned by Card and Socket Services. If address COM1
(3F8) or COM3 (3E8) are unavailable, the DSP-100 will not be configured. If the Client
Driver can successfully configure the DSP-100 its interrupt status register will be
enabled.

DSP-100 User's Manual 6

2.1.2.3 Example 3

DEVICE = C:\DSP-100\DSP100CL.SYS (s0,b300,i5)

In example 3, a single command line argument is provided. The Client Driver will
attempt to configure a DSP-100 inserted into socket 0 with a base address of 300H and
IRQ 5. If address 300H or IRQ 5 is unavailable, the DSP-100 will not be configured. In
addition, if a DSP-100 is inserted into any other socket, it will not be configured. If the
Client Driver can successfully configure the DSP-100 its interrupt status register will be
enabled.

2.1.2.4 Example 4

DEVICE = C:\DSP-100\DSP100CL.SYS (i5,u,b300)

In example 4, a single command line argument is provided. Because the parameter
order is not significant, the Client Driver will attempt to configure a DSP-100 inserted
into any socket with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is
unavailable, the DSP-100 will not be configured. If the Client Driver can successfully
configure the DSP-100, its interrupt status register will be disabled (Scratchpad
registers enabled).

2.1.2.5 Example 5

DEVICE = C:\DSP-100\DSP100CL.SYS (b300,i5) (i10) ( )

In example 5, three command line arguments are provided. The Client Driver will first
attempt to configure a DSP-100 inserted into any socket with a base address of 300H
and IRQ 5. If address 300H or IRQ 5 is unavailable, the Client Driver will proceed to
the second command line argument and attempt to configure the card with a base
address assigned by Card and Socket Services and IRQ 10. If IRQ 10 is also
unavailable, the Client Driver will proceed to the third command line argument and
attempt to configure the DSP-100 with a base address and an IRQ assigned by Card and
Socket Services. If the DSP-100 is successfully configured, its interrupt status register
will be enabled.

DSP-100 User's Manual 7

2.1.2.6 Example 6

DEVICE = C:\DSP-100\DSP100CL.SYS (b300,i5) ( ) (i10)

In example 6, the three command line arguments of example 5 have been rearranged.
The Client Driver will first attempt to configure a DSP-100 inserted into any socket with
a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the Client
Driver will proceed to the second command line argument and attempt to configure the
card with a base address and IRQ assigned by Card and Socket Services. Since the
second command line argument includes all available address and IRQ resources, the
third command line argument will never be reached by the Client Driver. It is the
user's responsibility to place the command line arguments in a logical order.

2.1.2.7 Example 7

DEVICE = C:\DSP-100\DSP100CL.SYS (s0,b300,i5) (s1,b340,i10)

The type of configuration shown in example 7 may be desirable in systems where more
than one DSP-100 is to be installed. In this example, the Client Driver will attempt to
configure a DSP-100 inserted into socket 0 with a base address of 300H and IRQ 5. If
the DSP-100 is inserted into socket 1, the Client Driver will attempt to configure it with
base address 340H and IRQ 10. This allows the user to force the DSP-100's address and
IRQ settings to be socket specific which may simplify cable connections and software
development. As in the previous examples, however, if the requested address or
interrupt resources are not available, the DSP-100 will not be configured.

DSP-100 User's Manual 8

2.1.3 Common Problems

Generic Client Drivers:

Many Card and Socket Services packages include a generic client driver (or
SuperClient) which configures standard I/O devices. If one of these generic client
drivers is installed, it may configure the DSP-100 causing the DSP-100 client driver to
fail installation. In these cases, the user should do one of the following:

1. modify the operation of the generic client driver to disable the configuration
of modem/serial port cards. Consult the Card and Socket Services
documentation for availability and details of this feature.

2. place the DSP-100 client driver before the generic client driver in the
CONFIG.SYS.

Available Resources:

One function of the Card and Socket Services software is to track which system
resources (memory addresses, I/O addresses, IRQs, etc.) are available for assignment
to inserted PCMCIA cards. Sometimes, however, the Card Services software assumes
or incorrectly determines that a particular resource is used when it is actually available.
Most Card and Socket Services generate a resource table in a file (typically in the form
of an .INI file) which the user can modify to adjust the available system resources.
Consult the Card and Socket Services documentation for availability and details of this
feature.

Multiple Configuration Attempts:

Some Card and Socket Services have a setting which aborts the configuration process
after a single configuration failure (such as a request for an unavailable resource). The
user should change this setting to allow for multiple configuration attempts. Consult
the Card and Socket Services documentation for availability and details of this feature.

Older Versions of Card and Socket Services:

Some versions of Card and Socket Services dated before 1993 do not support general
purpose I/O cards. If after careful installation of the Client Driver the DSP-100 does not
configure or operate properly, an updated version of Card and Socket Services may be
required. Card and Socket Services software is available from Quatech.

DSP-100 User's Manual 9

2.2 DSP-100 Enabler for DOS

IMPORTANT:

IMPORTANT:

exclude this memory region.

For systems that are not operating PCMCIA Card and Socket Services software, the
DSP-100 DOS Enabler may be used to enable and configure the adapter. This Enabler,
DSP100EN.EXE, will operate on any DOS system using an Intel 82365SL or PCIC
compatible PCMCIA host adapter including the Cirrus Logic CL-PD6710 / 6720, the
VLSI VL82C146, and the Vadem VG-365 among others.

In order to use the DSP-100 Enabler for DOS, the system
MUST NOT be configured with Card and Socket Services
software. If a Card and Socket Services software is installed,
the DSP-100 Enabler may interfere with its operation and
with the device(s) it controls.

The DSP-100 Enabler does not support automatic configuration of adapters upon
insertion, more commonly referred to as "Hot Swapping". This means the adapter must
be installed in one of the system's PCMCIA sockets before executing DSP100EN.EXE. If
more than one adapter is installed in a system, the Enabler must be executed separately
for each adapter. Furthermore, DSP100EN.EXE should be executed to release the
resources used by the adapter before it is removed from the PCMCIA socket. Since
PCMCIA adapters do not retain their configuration after removal, any adapter that is
removed from the system must be reconfigured with the Enabler after re-inserting it
into a PCMCIA socket.

The Enabler requires a region of high DOS memory when
configuring a DSP-100. This region is 1000H bytes (4KB) long
and by default begins at address D0000H (the default address
may be changed using the "W" option). If a memory manager
such as EMM386, QEMM, or 386Max is installed on the system,
this region of DOS memory must be excluded from the memory
manager's control. Consult the documentation provided with
the memory manager software for instructions on how to

DSP-100 User's Manual 10

2.2.1 Command Line Options

To configure a DSP-100 in the system, the Enabler requires one command line
argument from the user to determine the configuration of the card. This argument must
be enclosed in parenthesis and within the argument, any or all of the following
parameters may be specified using a comma (no spaces) to separate each parameter:

Ssocket specifies which PCMCIA socket the DSP-100 must be inserted into for this

configuration argument to be used. socket must be in the range 0 - 15. This
option is always required.

Baddress specifies a “block mode” base I/O address of the DSP-100 in hexadecimal.

This address must reside on an even 16-byte (10H) boundary. Specify only
one of the following three options: Baddress, Dmode, or ‘R’. Use of one of
these options is always required.

Dmode specifies a “COM” mode” base I/O address configuration for the DSP-100.

The ‘D1’ option configures the DSP-100 at COM1/COM3 (3F8 / 3E8), and
the ‘D2’ option configures the DSP-100 at COM2/COM4 (2F8 / 2E8). Specify
only one of the following three options: Baddress, Dmode, or ‘R’. Use of
one of these options is always required.

Iirq specifies the interrupt level (IRQ) of the DSP-100 in decimal. irq must be

one of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is
desired. This option is required if the 'R' option is not used.

Waddress specifies the base address of the memory window required to configure the

DSP-100. Set address = D0 for a memory window at segment D000, address
= D8 for a memory window at segment D800, etc. Valid settings for address
are C8, CC, D0, D4, D8, and DC. If this option is omitted, a memory window
at segment D000 will be used.

U instructs the Enabler to disable the DSP-100's interrupt status register and

enable the Scratchpad registers of the individual UARTs. This option is only
required in very rare cases where an application program requires access to
the UART's Scratchpad register. If this option is omitted, the DSP-100's
interrupt status register is enabled and the UARTs' Scratchpad registers are
disabled.

Before removing a DSP-100 from its PCMCIA socket, the Enabler should be executed to
free the system resources allocated when the card was installed. For this operation the
Enabler provides on additional command line option:

DSP-100 User's Manual 11

R instructs the Enabler to release the resources previously allocated to the

DSP-100. When the 'R' option is used, any settings specified by the 'B', 'I',
and 'U' options are ignored.

2.2.1.1 Example 1

DSP100EN.EXE

In example 1, no command line argument is specified. The Enabler will report an error
and display the proper usage of the command.

2.2.1.2 Example 2

DSP100EN.EXE (s0,b300,i5)

In example 2, the Enabler will configure the DSP-100 in socket 0 with a base address of
300H and IRQ 5 using a configuration memory window at segment D000. The
DSP-100's interrupt status register will be enabled.

2.2.1.3 Example 3

DSP100EN.EXE (i10,u,b340,s1)

In example 3, the Enabler will configure the DSP-100 in socket 1 with a base address of
340H and IRQ 10 using a configuration memory window at segment D000. The
DSP-100's interrupt status register will be disabled (Scratchpad registers enabled).
Note that the parameter order is not significant.
