[much deleted] OS/2 also uses the "prioritized interrupt handling" scheme. In any case, IBM seems to have given up on decent OS/2 serial drivers. Instead, their tech-support people now refer complainers to a shareware OS/2 serial port driver "sio.sys" However, this shareware driver also went through about 25-30 iterations as different pieces of junk PeeCee serial port cards gave people problems. A while back there was a lengthly article written in the December 1994 Dr. Dobbs by Bill Wells that covered a new serial driver for FreeBSD. I don't know if the current sio serial driver descended from that driver, but I assume that it did. That's what freely available source to the OS can do to improve things.
