>I have many simulators and some utilities that send and receive data via a serial port. this works fine in windows xp but on windows 7 the utilities never receive any data through the serial port. If I switch to the modem serial port and pass ATZ, it returns with an OK immediately so I know it is working. If I put any of the simulators (that basically continuously send data through the port) on com1 and then put another utility/simulator that reads data on another com port (or on another machine on a comm port connected via a cable) , the one receiving never fires the oncomm event of the mscomm control.

What happens if the transmitter is Win7 and reciever is Win XP? Have you tried using Hyperterm on the receiver side and see if you see any differences?
