Hi,

Has anyone any idea whether it's possible to monitor what data is being passed through a serial port?. I realise I can use MSComm to control input and output, but how about if I just want a vb program to echo whats being sent / recieved to the screen? ( effectively a 'peek' command that would read the I/O buffers but not take anything out of them ). I'm trying to control a serial driven wall display board but haven't got any technical information as to protocols it expects etc, however I do have the original control program, I just can't tell what it's doing.

Thanks
