Hello friends, has anybody knowledge about creating virtual serial ports, because I must write a program which can create virtual serial ports and be able to monitor the communication on these virtual serial ports. Thank you for your help in advance!:) szilard -- modified at 8:40 Thursday 16th March, 2006

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 ! Szilard SZ

Thank you for your reply Cedric :). I don't know if you have heard about the HHD Free Serial Port Monitor. That would be a good model for the programme I have to write. I don't know what tehnique they use. This HHD software monitors in a passive mode al the communication done by other software through the serial port, I don't think it opens the port otherwise it could block the communication for other software. I also have another question, what if I use assembler code, embedded C or something like that, and integrate in my visual C++ code? I think there has to be a possibility to read the memory location through which the serial communication is done. Thanks in advance ! Szilard Szilard
