Friends ! I need help !
I have to write a programme in Visual C++ 6 which can listen or sniff the serial port, but without opening the port. The sniffer and the programme which communicates through the serial port has to be on the same PC, I have to write a program which can read ( or listen ) the data that goes out and comes in from the serial port, BUT NOT TO OPEN THE PORT, to let communication programmes communicate through serial ports.
If anyone has an idea how to write this sniffer programme, please send me a advise.
Many thanks !
