That will not work anymore if you use a reading thread, as SendCmd()
performs its own reading internally.  So you have the possibility of the
thread receiving data that SendCmd() is expecting, and vice versa.

Simply call one of the appropriate reading methods of the connection in a
loop for the lifetime of the thread.  Look at the source code of the
TIdTelnet component for an example.
