>>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
