This is exactly (what I think :) I want.
I want a dedicated client for each SerialPort cause in accordance with
the master/slave polling philosopy you can only address one device at a
time on a specific port - and *have to* wait until you receive a
response or timeout occurs. My multithreading driver allows you do do
this on a bunch of ports concurrently.
Thanx for the feedback though - I'm going to mess around with
application.internet a little more (along the same lines of deprecated
UDPClient) and see how far that gets me.

Eugene
