According to the manual, each port has corresponding drivers for polled mode or interrupt driven mode. Well, where to the interrupts go when they occur? Is there any way to catch com port interrupts for reading the com port when data is present rather than polling the port? I was hoping to find a signal called "SIGCOM" (BSD like), which would do the trick, or "select" (also BSD). Perhaps there is some other way I am unfamiliar with? Thanks for any suggestions! Mark
