>>HELP!!<<
I am at a total loss to explain what's happening with my COM port #2,
If I power up the machine and do nothing, port 1 works fine, and port
2 looks like it's there, when I start up a terminal emulator the DTR
lite on my modem goes on, but when I type nothing goes to the modem,
and nothing comes back, but if I run a diagnostic program called Checkit
on this port, then I try to use the port all is fine.
I know very little about the internals of serial ports and such,
Does anyone have an explanation for this phenomenon? And better
yet, might someone be able to provide me with a piece of code,
preferably in C that will do whatever tweaking to the COM port to
make it avtice. Any help that anyone can provide would be
greatly appreciated. Please reply directly to me, as I don't
have much time to read this newsgroup. Thanx

I assume you are using a external modem. Is the modem and COM2: set up the same? Are both 1200 baud (or whatever is the correct baud rate), the same number of stop bits, data bits and parity? Your symptons are typical of such a mismatch.
