I'm using RS232 to transmit and receive characters between a dsPIC33 microcontroller and a computer. I'm not getting any output at the computer terminal. I tried to see the received characters on HyperTerminal as well as Flash Magic terminal.
I checked the Rx and TX pins of the microcontroller as well as the DB9 connectors on an oscilloscope. Here I'm getting a proper signal waveform with correct voltage levels(3.3V at microcontroller pin and +12/-12V at DB9). Both end of the serial cable also show correct waveforms.
Yet there is no output at computer terminal.I also sent a character from the computer and wrote a code in the dsPIC33 to glow an LED if the char is received. Yet no output.
Are there any COM port/terminal settings that I'm missing? How do I debug this?
