APPENDIX B PC COM98 DEVICE DRIVER FOR MS/DOS B.1 PCCOM Software The PCCOM V2.0 is a
high performance, easy to use RS232/RS422 device driver for PC/XT,
PC/AT, PC/386, 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.
The PCCOM V2.0 is an
upgrade version of PCCOM V1.0 software, it combines with PCCOM V1.0 and
SERIAL DRIVER utilities. Each serial port may be either 8250, 16450,
16550, or 16650 chip that was detected automatically.
