I do this for connecting to ADAM modules which are running MODBUS servers on port 502.
I use threads as the tcp timeouts in Win32 don't work since I have to connect to 27 of these. it takes about about 20 seconds for the thread to timeout and die if the host I'm trying to connect to isn't there...and that's fine, works for me. What are you doing that it takes 5 minutes to timeout?
