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

<----------------------[snip]--------------->

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

One thing I have noticed is that the IRQs will not show up unless something is actually using the device. For serial ports, the IRQ will not show up until something opens the port. Something on the line of if there isn't anything that is going to process it, the IRQ is disabled, and does not show up in the list.

I don't know if it will help, but you may want to check with setserial to see if it is detecting the correct UART type. You can also try adjusting the FIFO settings. If the driver is treating the UART as if it does not have a FIFO, or if the FIFO settings are wrong, then the serial port will generate too many interrupts. It is possible that it is generating one interrupt per character sent/received.
