serial interrupt

[hadjrami]

Hello

I want to exchange data with a device connécted to a sérial port. I can communicater using pulling but don't know how to use interruption. I read documents from the site but I didn't find any example.

Thinks for your help

I am new to serial communication, but I would like to promote discussion so sorry if these sound like unintelligent questions.

First, are you trying to experiment with sending or receiving data?

Are you trying to control the IRQ? If so, how would you like the IRQ to behave differently?
