| This driver support PC/xI (PC/8i, PC/16i),
PC/2e and PC/8e DigiBoard serial communication boards.
The PC/8i and PC/16i have dip switches to setup the board memory
address, I/O port number and interrupt number. Jumpers J1, J2 and
J3 should all be set to 2 and 3. The memory address must start on
64K boundary and uses 64K of memory. The highest address that can
be used is 0xf9000. The possible I/O ports numbers are 0x100,
0x110, 0x120, 0x200, 0x220, 0x300 and 0x320. The possible interrupt
numbers are 3, 4, 5, 7, 10, 11, 12 and 15.
The PC/2e and PC/8e have dip switches to setup the I/O port
number only. The interrupt number and memory address are set by
software. The memory address must start on 8K boundary and uses 8K
of memory. The possible I/O ports numbers are 0x100, 0x110, 0x120,
0x200, 0x220, 0x300 and 0x320. The possible interrupt numbers are
3, 4, 5, 7, 10, 11, 12 and 15.

DCD(data-carrier-detect) is receive enable and CTS (clear-to-send)
is transmit enable. Receive characters only if DCD is high.
Transmit characters only if CTS is high. If -t is not used and when
sending the first character of a new transmission, it will wait up
to 500 milliseconds for both DCD and CTS to be high before
transmitting. Otherwise the whole transmission is abandoned |
|
|
-t |
Raise RTS only
when transmitting. |
|
|
-i |
String Dial
modem string. This string is sent whenever the port is initialised.
Special characters are |
