    I need some help on using this pre-historic application: hyperterminal.
    I need to send some commands to a COM port. Im doing this: new connection > give connection a name and an icon > select COM3 port and 115200kbaud > OK > type some text and press ENTER.

    I have a loop-back circuit so I expect to receive what I type. However when I press enter and didn't see nothing.

    Any suggestions?

    For "debuging my skills" with hyperterminal Im using a C# app I made some time ago which also sends and receives dada from COM ports. With this application I have no problems so I guess Im doing something wrong in hyperterminal.

    In your loop back circuit, are you emulating CTS/RTS handshaking? If not set the handshaking to none in the commport properties... or jumper pin 7 (RTS) and pin 8 (CTS) on the serial port...
