[comp.sys.ibm.pc] Using serial port on a PC/AT

duane@schizo.samsung.com (Andrew Duane) (06/07/90)

I am trying to hook up a terminal to the serial port on a
PC/AT 386 clone (a Samsung, to be exact, but I have failed
on others, too). The problem is that when I try to write a
character to the port, I get back a "write fault/timeout".

I have tried every combination of null modem/straight through,
3-pin/5-pin/7-pin, full/half duplex, etc. I know the problem
is not my end, since I even failed on a box that can talk to
a PROM burner and an ICE on COM1. When I plug a terminal into
the same port, I get the error.

HELP! Who could believe that such a simple operation on a simple
box could be so difficult.  As expected, there is no documentation
to help me, and I am at wits end. BTW, in case you are wondering,
we are not using DOS, but a special ROM-based application that
needs to speak to a terminal as a console device. The terminal
is only needed for output; no keyboard input is required.

Please E-MAIL, as I do not read this group.
