Hi :

I'm trying to remotely control a text mode app.  In this case, Telnet.
 I have some code, but it doesn't work properly.  It allows me to
receive text from it, but not write to it.  I'm probably doing
something stupid, as it looks like an easy technique.  If someone could
point me in the right direction, or even to some reference, my life
would be a better place to be.

Note that I can type into the window running this program and the
output will go to COM2.
