I have an inc.jet printer that speaks only in a complex series of non-printable characters. I need to pass the printer on the TCP port a series of bytes. my initial tests are failing. I'm looking for a means to test the values going to the printer to see what is actually going out on TCP. Is there a tool which I can use to see the values posted on to the network?
My attmpts are getting a buffer back, but its an error message. not the response expected. So I think my message is buggered to the port.
I need a better tool to debug the comms.
