I'm using async sockets, and overriding the OnReceive, but it doesn't
receive
anything. I also tried introducing sleep timers, but that didn't help it
either. Do you have to send it character by character? I'm sending the
entire command as a string.

You can certainly send an entire command as a string. But that does not
mean the string will all be received at once. That part is timing
dependent. If you are assuming that every call to Receive gets you the
exact amount of data that a call to Send sent then you are making a
classic beginner's misunderstanding about sockets. If you don't get all
the data in one call to Receive then you must wait for the rest.

OP is not writing the Receive paired with his Send, as far as I can tell.
OP is writing both send and receive for one end (the client end) of a telnet
connection.
