How can I find out what's the IRQ it uses?
How can I change the IRQ?
I deal with computers for more than ten years now, but I never was a
hardware guy. Installing a hard drive was as far as it went :(.

See your manual and/or cat /proc/interrupts

See your manual.

PC hardware sucks.  It's a true testament to Linux that crappy hardware
design (why are there these stupid "ISA" slots?  why is it such a
damned pain to insert a *y SIMM?  why can't I really use COM3 and
COM4 without fighting IRQs?) can still make a useful system.

Not really, just isa sucks ... pci shares like crazy, he could get a pci
modem, set his motherboard to level instead of edge trigger, it should work
fine...in fact on my system I have . . . PCI parallel and serial, video,
sound and  satellite adapter all on irq 11, and usb on irq 10...I did have
to hack the kernel for pci parallel and serial support though...although on
just serial (or modem) he could just cat /proc/pci and
use the port and irq for his setserial command.

I had a look at the Serial-HOWTO, but serialously (p.i.), since it is
obviously not an IRQ problem, that isn't of much help.

Perhaps some of the messages about a missing "broadcast" module at
startup have something to do with this? Diddling with the MRU didn't
change anything.

Look, guys, I am really desperate. Isn't there anyone running an
external USR Sportster ISDN TA?
It's such a slick little machine, it's more compatible than most
people will ever need (Acorn, Amiga, Atari ST, Apple ][?), I wonder
why I simply can't get it to work!

Especially in a 1996 Packard Bell box. :-(( <arrghh> A friend of mine
had to virtually hammer it into the slot while I held the hard drive
cables up that were stretched so tightly across the RAM banks that it
was impossible to simply push them aside.

It should:

 3:   13931655 + serial
 4:    2443647 + serial

Does anything work on that port?  Is this a COM3/4 problem?  [In short,
COM3/4 share IRQs with COM1/2, which is stupid.... but that's PC
hardware... gotta be compatible with old 286's and a pair of cascaded
8259a's, even though they no longer exist...]

Are you sure?  It should show up in /proc/interrupts if it's set up
right.

What sort of mouse do you have?  Serial?  Does it show up there?

What's a broadcast module?  Is that message still hiding in 'dmesg'?
I'd love to see it.  You shouldn't need a kernel module to broadcast.
(Unless your serial port or ethernet is built as a kernel module, I
guess...)

Be grateful it didn't catch on fire.  PB's like to spontaneously
combust.  I just wish Sun hardware were more affordable.... it's NICE to
work on a Sun.

It is not a COM3/4 problem. My box hasn't even got a COM2.
Just a 9-pin COM1... that's a packardbellism, I suppose. I had a hard
time getting the Sportster connected to it (bought and brought back
two adaptors before I found the right one).

The serial port doesn't show up there.
I wonder why the modem works at all?

My mouse is PS/2.

Don't know.

The kernel just says something along the lines of "missing module:
broadcast" twice at bootup, interspersed with other messages. I am
under Windoze right now (no fast connection under Linxu...). Next time
I boot over I'll bring you the messages.

Oh really? Perhaps that's because even the Pentium 133 models haven't
got a CPU fan.

I suppose so. Macintoshes must be nice, too. I heard the most
wonderful stories about boxes without a single*and power
supplies folding away in Macs.

Weird.

IRQ4 would be shared with COM2, so it shouldn't have a problem with
sharing if you don't have a COM2.

Quote:> The serial port doesn't show up there.

I dunno: it SHOULD be there.

Then it should be on IRQ12.

Cool.

Gack... even my P120 get damned toasty with a fan.

Some are.  Our Macguy whines about some models being almost as much a
pain as PCs to work on.

On my system, it only shows up in /proc/interrupts when PPP is
actually running.  It's probably the same on Matthias' system.

        Very interesting. What's the difference between level and edge trigger?

        Thank you!

Actually, the /proc entries are only active if the port is open()ed, so
something like "cat < /dev/<port> &" while you check the port settings
(don't forget to kill off that background process afterwards) should work.
