| This driver support MC/xI DigiBoard serial
communication boards with 128K of memory.
Boot the system to run the IBM Automatic Configuration program
to setup the boards address, I/O port number and interrupt number.
The possible memory addresses are 0xFC00, 0xFA00 and 0xF800 uses
64K of memory. The possible I/O ports numbers are 0xF1F0, 0xF2F0,
0xF4F0, 0xF8F0. The possible interrupt numbers are 3, 4, 5, 6, 7,
9, 10 and 11.

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. When sending a new
transmission, both DCD and CTS must be high, otherwise the whole
transmission is abandoned. |
