Server 2008R2 has four serial ports.

Program that i want should listen on all ports

and catch input data (strings)

if match is found- other data should be send to one of this ports.

for illustration, if "HELLO" comes from COM1: than "DF109" should be sent to COM4:

when something is written to the port program should verify for feedback "OK" or similar.

powershell coding can be preferred
