[fpc-pascal] Serial port interrupts?

[John Coppens]

Hello people.

To make a debugging tool, I need to time changes on the serial port
control and status lines on a Linux machine. The serial port hardware has
this possibility, but is it possible to program this in a more
or less high-level way? I did this a long time ago in DOS. 

I've looked at several libraries, but none seem to give access to
line/status change events in realtime.

Thanks in advance,
John
