  I am trying to write an interrupt driven serial port program using C, and I was wondering if anyone have amy idea if this is possible. My Unix system supports POSIX termios.h and aio.h, will my answer lies within these two include files?
   Fundamentally, I would like to send a string of commands out of my serial port and proceed with other task. In the background I would like to have an interrupt handler that continously read the in-coming buffer for a full length string return data. I don't want to hang the system on the read process because of the my process is under real-time.

Use select(), or poll(), or pthreads, or asynchronous I/O.

You could also set VMIN and VTIME with the <termios.h> API.
