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.
For more details, please refer PCCOM manual.
