You can first test the port by connecting the com ports externally, then use
HyperTerminalto test the connection. RunHyperterminaltwice, one for each port, and communicate between them; if it runs ok, then run your program on one end at a time, and communicate with HyperTerminal; that way you can find where the error is. this is this. -

I havent tried with the virtual ports but it seens that the Hyperterminal solution is good one to try . :cool: Vikas Amin Embin Technology Bombay vikas.amin@embin.com
