Testing serial port communication

[daveD]

Hi,

I am trying to set up a bluetooth printer for a mobile device. I have set the printer up to have an outgoing COM port but I am having no luck.

I would like to write a small test app to check if I can communicate with the port. Is there a way to "ping" a COM port?


Thanks,
Dave

You could write this test byte back. Say you have a function to send a byte to the serial port, next just write one that reads this byte back. If you have more hardware debug devices, i.e., oscilloscope or you might try some leds on a breadboard, it also would help.

THere are serial port sniffers outthere too, just google for a good one.
