Robert,
I've followed your advice. The BIOS had already been set a non PnP OS. I
recall now that the manual advised this when I was putting the machine
together.

I also noticed that under the PnP options in the BIOS there was an option to
set the modem IRQ. This was set at 3 and so I changed it to 5. This had no
effect whatsoever either under Linux or Win.

OK the next thing was to cat /proc/interrupts, the output was as follows

	CPU0
O	479486	XT-PIC	timer
1	169		XT-PIC	keyboard
2	0		XT-PIC	cascade
8	1		XT-PIC	rtc
9	0		XT-PIC	emu10k1
10	0		XT-PIC	usb-uhci
12	7		XT-PIC	PS/2 mouse
13	4581		XT-PIC	fpu
14	17		XT-PIC	ide0
15	0		XT-PIC	ide1

If I am reading this correctly then it would appear that both IRQ 4 (what
the modem is currently assigned) and IRQ 5 (modem under DOS) or both free.

Also I was reading something about IRQs in "Using Linux", Ball, Que in which
a table indicates that ttys0 and ttys2 use IRQ 4 and that ttys1 and ttys3
use IRQ 3.

Is this set in concrete then or can it be changed so that /dev/modem linked
to ttys2 can use IRQ 5.

As you can see I am not entirely sure of what to do, (newbie).  Nevertheless
the responses posted to my queries along with all the reading HOW TOs etc
are helping to improve my knowledge.

Thankyou all graciously

David Underwood.

PS /dev/modem was linked to ttys2 not ttys02 already. Sorry my poor typing.
