Lordy Rick, I'm an old BBS sysop from back when. I have a RS Robotics
external with all the bells and whistles in hardware, so I'm connected
only by a serial cable. I'm gonna check out your suggestion about the
IRQ though. I sure miss setting pin jumpers. Devices generally stayed
where you put 'em, IRQ wise. Here's /proc/interrupts

# more interrupts

I don't see IRQ 3 or 4 listed for serial port. Do I have to gink with
uugetty or set serial? Is that the right place to look?? Ric
