INTRODUCTION
The PCCOM ISA bus 2
port serial adapter provides two asynchronous serial communication
ports (RS232), which link the computer and serial peripheral devices
such as terminals, modems, serial printers, plotters, ... etc.
The PCCOM ISA bus 2
port adapter is particularly suited to facilitate the connection of
terminals (VDUs) in multi-user operating systems. Each board is
supplied complete with many kinds of connectors.
The PCCOM ISA bus
board may be installed in any PC/486, Pentium or hardware compatible
systems. To accommodate a variety of operating systems, six jumper
blocks permit maximum flexibility of configuration. You may select
which interrupt (IRQ2 - IRQ15) and I/O address you desire.
The PCCOM ISA bus 2
port board can be addressed anywhere within the full range of PC I/O
ports and each port address can be set individually as your
requirement. The interrupt selection features also provide individual
interrupt selection for each port, so that you can arrange the 2 ports
in any combination of interrupt you need.
The PCCOM ISA bus 2 port board can be used to plug in 8250, 16450,
16550, or 16650 chips, and the PCCOM device driver can detect it
automatically. There are two kinds of board can be choose, one is
normal speed card that its baud rate up to 115200, another is high
speed card that its baud rate up to 460K.
The features of the PCCOM ISA
bus 2 port adapter are:
|
Two RS232 ports for
asynchronous communications. |
|
Suitable for
XENIX/UNIX (SCO, AT&T, Interactive, UNIXWARE), MS/DOS, MS/WINDOWS,
WINDOWS/NT, WINDOWS/95, OS/2, WINDOWS/98, WINDOWS/2000, PICK,
CONCURRENT DOS, QNX, PROLOGUE, MUMPS, ... etc. |
|
PC/486, Pentium
hardware compatibles. |
|
ISA bus Interrupt
selectable. (IRQ2 – IRQ15) |
|
I/O address
selectable for each port. |
|
Interrupt selectable
for each port. |
|
Auto-detect 16450 or
16550 or 16650 chips on board. |
|
Baud rate up to
115200 for normal speed board and up to 460K for high speed board. |
