Hi... What is the command for 'EchoOff' & 'EchoOn' in C# for SerialPort communication in C#. Regards, Vinay
Sounds like what you are really talking about it the echo from a modem, the serial port itself has no echo. If I am right it all depend on the modem you are using. Most "Hayes" modems use &E0 and &E1.
