APPENDIX B
PCCOM DEVICE DRIVER FOR
MS/DOS
B.1 PCCOM Software
The
PCCOM software is a high performance, easy to use
RS232/RS422 device driver for PC/486, Pentium or compatibles. Under
MS/DOS environment, you can set up your serial ports by PCCOM device
driver, and these serial ports can be treated as COM1: and COM2:
devices. The setup procedure provides flexible functions to specify the
configuration of multi-serial card, that is, the hardware
configurations of I/O port number, I/O port address, interrupt and
interrupt vector are user selectable.
After the device driver is installed,
It takes over communication between CPU and multi-serial
cards such as four port card, eight port card, ... etc. For
each I/O port, the service routine handles a ring buffer to keep track
of all I/O data. Moreover, the PCCOM software provides library routines
(C, PASCAL, BASIC, FoxPro) and DOS communication interface (DOS device
driver, BIOS call) for several access levels.

PCCOM manual

B.2 Software Installation
When the board is installed, please install
software drivers as follows:
STEP 1: Prepare PCI.OPT file
The PCI.OPT file contents
are :
/B:4
/D:COM3
/P:[:4:(2k:9600:N-8-1:RTS+DTR:XON)
* 4
|
STEP 2: Prepare CONFIG.SYS file
Insert statement into CONFIG.SYS file
For normal speed
DEVICE = PCCOM.SYS
@c:\pci.opt
|
For
high speed
DEVICE = PCCOMH.SYS @c:\pci.opt
|
The
syntax of PnP function is
The Card_id field is defined as 1 or 2
or 3 or 4 or nil, if you use PnP mode, just fill nil in
card_id field that like step 1, otherwise you can specify
card_id to match the card identifier switch. The Portno field is used
to specify number of ports in this adapter. The Port field is defined
as PCCOM V2.0.
If more
than one PCCOM board is installed,
Please repeat directive /P of the step 1. |
