1.2 Supported Serial Port Adapters

{All Quatech serial adapters

{Standard (legacy) single serial port hardware such as built-in motherboard ports.

{Multiport serial adapters from manufacturers other than Quatech are not supported.

Performance is enhanced by the interrupt status register found on Quatech PCI and

PCMCIA serial adapters and on most Quatech multiport serial adapters for ISA and Micro

Channel (MCA) bus computers. The driver also supports the Quatech ESI-100Q intelligent

eight-port serial adapter.

1.3 Requirements

{OS/2 version 2.11 or later (earlier versions do not support PCI devices)

{Approximately 50 kB of hard drive space

{The Interrupt Status Register on Quatech serial adapters must be enabled

1.4 Driver Components

{QCOM.SYS physical device driver (replaces IBM's COM.SYS)

{QVCOM.SYS virtual device driver for DOS support (replaces IBM's VCOM.SYS)

Quatech Asynchronous Serial Device Driver for OS/2 2

2 Installation

This device driver set is designed to be a direct replacement for software modules

supplied by IBM in the OS/2 product. Installation is simple, and changes needed in other

portions of a currently working system are minimal. A system backup is suggested before

installation.

If "Serial Device Support" was not selected during OS/2 installation or a subsequent

Selective Install, the IBM drivers may not be present on the hard drive. This will not affect

installation of the Quatech drivers.

2.1 Preparation

Will Quatech PCI serial ports be used?

If yes, ensure that the jumpers labeled "X2", "X4", "X8" and "SPAD" are removed or

are installed in neutral (spare) positions. Removing the "SPAD" jumper enables

the interrupt status register.

Will Quatech ISA serial ports be used?

If yes, record the adapter's base address and IRQ. Ensure that the DIP switch is set

to enable the interrupt status register. For certain newer adapters, this may be done

by removing the "SPAD" jumper instead of with a DIP switch. For the DS-100,

record the base address and IRQ of each serial port.

Will Quatech PCMCIA serial ports be used?

If yes, ensure that the appropriate Quatech OS/2 PCMCIA Client Driver device driver

has been installed according to the documentation that accompanied those drivers.

The client driver should be listed in the CONFIG.SYS file below the QCOM.SYS

device driver.

Will Quatech Micro Channel serial ports be used?

If yes, record the adapter's base address and IRQ. The interrupt status register may be

optionally enabled for slightly enhanced performance. For installing a Quatech

Micro Channel adapter, see page 16 first.

Will built-in motherboard (chipset) serial ports be used?

If yes, record the adapter's base address and IRQ.

Quatech Asynchronous Serial Device Driver for OS/2 3

Will other serial ports made by manufacturers other than Quatech be used?

Quatech's device drivers will operate any serial port that appears to be a standard

(legacy) serial port. For these ports, record the port's base address and IRQ.

Quatech's device drivers will not operate third-party multiport serial adapters.

2.2 Install the Files and Add Configurations

1. Copy QCOM.SYS from the installation disk to the \OS2 directory on the boot partition.

Copy QVCOM.SYS from the installation disk to the \OS2\MDOS directory on the boot

partition. These locations are suggestions; you may elect to use other directories if you

like. Do NOT delete the IBM device driver files.

2. Edit the boot partition's CONFIG.SYS. Comment out entries for COM.SYS and

VCOM.SYS, if present, by inserting "REM " at the start of the line. Immediately

following these commented-out entries, or at the end of the CONFIG.SYS file, add

entries for the Quatech device drivers:

DEVICE=d:\path\QCOM.SYS (parameters) ... (parameters)

DEVICE=d:\path\QVCOM.SYS (parameters) where

"d:\path" indicates the drive and directory path where the Quatech drivers were copied.

Parameters are discussed below.

3. Save the edited CONFIG.SYS, shutdown the system and reboot.

2.3 QCOM.SYS Parameters

The basic parameters for QCOM.SYS are the same as those for IBM's COM.SYS. Extra

optional parameters have been added for Quatech adapters. All parameters are case-insensitive,

and do not include the quote marks in the descriptions. Parameters not marked optional are

mandatory.

All parameter sets must be enclosed by a pair of parentheses. Global options must reside

outside of any pair of parentheses. There should be no spaces within a pair of parentheses.

There must be at least one space separating each set of parameters.

The format for the parameters depends on the type of serial port being installed. A set of

parameters is needed for each device, with Quatech multiport adapters counting as one device.

Parameter formats are discussed below.

Quatech Asynchronous Serial Device Driver for OS/2 4

2.3.1 Quatech PCI Serial Port Adapters

Parameter format: (id,port,flags)

id Quatech adapter ID

This field corresponds to the product name, and should contain one of the following:

"DSC-100" for Quatech DSC-100 two-port PCI adapter

"DSC-200/300" for Quatech DSC-200/300 two-port PCI adapter

"QSC-100" for Quatech QSC-100 four-port PCI adapter

"QSC-200/300" for Quatech QSC-200/300 four-port PCI adapter

"ESC-100D" for Quatech ESC-100D eight-port PCI adapter

"ESC-100M" for Quatech ESC-100M eight-port PCI adapter

"SSCLP-100" for Quatech SSCLP-100 one-port low-profile PCI adapter

"SSCLP-200/300" for Quatech SSCLP-200/300 one-port low-profile PCI adapter

"DSCLP-100" for Quatech DSCLP-100 two-port low-profile PCI adapter

"DSCLP-200/300" for Quatech DSCLP-200/300 two-port low-profile PCI adapter

"QSCLP-100" for Quatech QSCLP-100 four-port low-profile PCI adapter

"QSCLP-200/300" for Quatech QSCLP-200/300 four-port low-profile PCI adapter

port Starting port number, 1 or 2 decimal digits

The first port on the adapter. The other ports on the adapter follow in contiguous sequence. For

example, to install a Quatech QSC-100 four-port adapter for COM9 through COM12, use "9" or "09".

flags Option flags (OPTIONAL --- Use only if needed)

Flags may be placed in any order, separated by commas. Some are mutually exclusive, in which case

the right-most flag will be the one used.

Consecutive spurious interrupt control (mutually exclusive):

"D" = Disable port after 1000 (default), "I" = Ignore, "P" = Post to application

UART selection override control (mutually exclusive):

"F5" = Limit to 16550 mode (16-byte FIFOs)

"F4" = Limit to 16450 mode (no FIFOs)

The driver defaults to 16450 mode and automatically detects a 16550 or 16750 if present. The

override should be used only if the user wishes to limit the FIFO size.

“O” = Make this PCI adapter optional. If the PCI adapter is not installed in the computer at boot

time, the driver will display a warning message and continue to load. This option flag is supported only

for PCI devices.

“OQ” = “Quiet” version of “O” option. The warning message is not displayed on the screen, but

will be written to the log file if the /D option is used (see section 2.5).

Example: (QSC-100,7)

A Quatech QSC-100 four-port PCI adapter providing COM7 through COM10 is installed.

The base address and IRQ used by the board are automatically assigned by the system and

detected by the device driver.

2.3.2 Quatech ISA and MCA Serial Port Adapters ("QS" and "ES")

Parameter format: (id,port,io,irq,flags)

id Quatech adapter ID

"QS" for Quatech QS-xxx or QS-xxxx 4-port adapter

"ES" for Quatech ES-xxx or ES-xxxx 8-port adapter

Quatech Asynchronous Serial Device Driver for OS/2 5

port Starting port number, 1 or 2 decimal digits

The first port on the adapter. The other ports on the adapter follow in contiguous sequence. For

example, to install a Quatech QS-100 four-port adapter for COM9 through COM12, use "9" or "09".

io Base I/O address, 3 or 4 hex digits

The base I/O address of the starting port. The value must match the adapter's address DIP switch

settings. The other ports on the adapter reside at increments of eight bytes in contiguous I/O space

following the first port.

irq Interrupt (IRQ) level, 1 or 2 decimal digits

The hardware interrupt level (2-15) used by all ports on the adapter.

flags Option flags (OPTIONAL --- Use only if needed)

Flags may be placed in any order, separated by commas. Some are mutually exclusive, in which case

the right-most flag will be the one used.

Consecutive spurious interrupt control (mutually exclusive):

"D" = Disable port after 1000 (default), "I" = Ignore, "P" = Post to application

UART selection override control (mutually exclusive):

"F5" = Limit to 16550 mode (16-byte FIFOs)

"F4" = Limit to 16450 mode (no FIFOs)

The driver defaults to 16450 mode and automatically detects a 16550 or 16750 if present. The

override should be used only if the user wishes to limit the FIFO size.

Example: (ES,17,320,3)

A Quatech ES-xxx eight-port non-intelligent adapter providing COM17 through COM24

is installed at base address 320 hex using IRQ3. The eight ports will be located at base addresses

320, 328, 330, 338, 340, 348, 350 and 358 hex.

Quatech Asynchronous Serial Device Driver for OS/2 6

2.3.3 Quatech intelligent "Q-suffix" series products

Parameter format: (id,mem,port,io,irq)

id Quatech adapter ID

"ESI" for Quatech ESI-xxxQ intelligent 8-port adapter

Any other value will cause an installation error.

mem Memory window address, five hex digits

The hexadecimal base address of the memory window used by the adapter. This value must match the

adapter's address DIP switch settings.

port Starting port number, 1 or 2 decimal digits

The first port on the adapter. The other ports on the adapter follow in contiguous sequence. For

example, to install a Quatech ESI-100Q eight-port adapter for COM8 through COM15, use "8" or

"08".

io Base I/O address, 3 or 4 hex digits

This is the simulated base I/O address of the starting port on the adapter (indicated by "port"). The

other ports on the adapter are simulated as residing at increments of eight bytes in contiguous I/O space

following the first port.

This field is used to simulate I/O space for the adapter in order to allow DOS and Windows sessions to

access the serial ports. The virtual device driver will capture access to this I/O address range and map

these accesses to the memory-mapped serial ports. If no DOS or Windows applications will be used

with the ports on the adapter, this field can be set to "000", and the adapter will use no I/O space.

Even though the intelligent adapter does not actually use any I/O space, if this field is non-zero, the I/O

space set aside for the adapter must actually be unused by any other device.

irq Interrupt (IRQ) level, 1 or 2 decimal digits

The hardware interrupt level (2-15) used by all ports on the adapter.

Example 1: (ESI,D0000,10,280,12)

A Quatech ESI-100Q eight-port intelligent adapter providing COM10 through COM17 is

installed in a memory window starting at D0000 hex using IRQ12. DOS applications will find

the ports at I/O base addresses 280, 288, 290, 298, 2a0, 2a8, 2b0 and 2b8 hex.

Example 2: (ESI,D0000,10,000,12)

A Quatech ESI-100Q eight-port intelligent adapter providing COM10 through COM17 is

installed in a memory window starting at D0000 hex using IRQ12. DOS applications will not

have access to the ports on this adapter, as no simulated base I/O address is specified.
