[-- Attachment #1 --] Hi, I am having trouble setting up a SIGIO for the serial port, the point in question is that when I do a fcntl(fd,F_GETOWN) or fcntl(fd,F_SETOWN,...), I get an "Inappropriate ioctl for device". I have used "signal" and a signal handler, and have set the serial port to "O_ASYNC", but this third requirment (as per all the books I have) just will not work. Is it a user rights issue, or am I way off track? I have tried various other ideas, fcntl(fd,FASYNC), ioctl(fd,TIOSPGRP)..., etc, etc, but all with various error messages. I have even tried locking the fd, then unlocking afterwards, no change.
