This is a re-post--I didn't receive any replies with a California
distribution, so I'm trying "world".



I have a problem with my serial port (on my Unisys AT clone).  I
can't send output to it using fopen("com1:", "w") from Microsoft
C, and "copy con: com1:" doesn't work (it accepts keyboard input,
but nothing comes out of the serial port).  When I type in
"mode com1:12,N,8,1" (or even just "mode com1:"),  I get the error
message "invalid parameter com1".  Despite this, Procomm, Telix, and
Crosstalk XIV all have no trouble with the serial port, and my
diagnostics disk tells me that I do indeed have a serial port
installed.  Does anyone have any idea what might be wrong?

Please send all replies to foote@ernie.berkeley.edu.

Thanks in advance,
