I have my modem and my UPS both connected to serial ports with the same
interupt. Seems to work OK. These are both on the same card which was
modified (not a lot of fun) to share the interupt. JDR Microdevices
sells a 4-port serial board that is supposed to support shared interupts.

Hi all!
I've read a discussion about serial ports and interrupts and still have
some doubts.
WHY KERNEL'S SERIAL DRIVER IS WRITTEN IN THIS WAY THAT IT'S IMPOSSIBLE TO
SHARE INTERRUPTS?
>From the hardware point of view it should be quite possible. The interrupt

So I have taken every port to it's own interupt. But my question is: Why
can I share interupt with parallel ports? I have lp1 and lp3 on the same
interupt, and printing and the access to my Zip drive works fine!
Chances are that, under Linux, lp1 is not really using an interrupt.
The defa
The parallel port kernel driver doesn't use the interrupt by default, it uses
polling. (It even says so in the boot messages, at least with my kernel.)

Cool! I've got a Psion S3a on a ttySx port attached.

I have a SIIG serial port ISA card so I can add on two more serial
ports.
I was looking through /etc/rc.boot/0setserial to see how everything is
configured, and I noticed that in the manual configuration section, it
attempts to setup the "COM1/3" and "COM2/4" ports to irq's 4 and 3,
respectively.
