openning/closing the com port

[gadi]

I m trying to write a protocol for rf Tx & Rx . Do anyone has any idea for massage to open/close the serial port automaticly?
I got lot of noise at the end of trannsimition.
basicly my problem is to get read of garbage - how can i close the port (mark the end of masssage ?) without getting the garbage?

:) I don't understand something here. I have no idea what can be sent to the serial port in order to open it? Especially if it is close. Or what do you mean? What kind of message you want to send and where?

There have been at least 3 threads here in the past week that give complete examples of controlling and communicating with the COM ports using API calls. I strongly suggest that you search the C++ forums to avoid duplication.
