Sorry, I didn't realize that switching the drives changed
the problem. I missed that. Anyway, drives usually use
IRQ14 or 15 so perhaps there's a hint there. Exactly what
IRQ _does_ the drive use?

If there is only one comport then it will always be com1
to DOS, that is the way it is set up unless you use some
workaround.
I think what is happpening here is that ctty expects
com1 to be IRQ4 and so does the mouse driver. A program
which acceses the comport will almost certainly have to be
made aware that it is now on IRQ3. Using non-standard IRQs
is an excellent way to get a headache. <g>
Put in another card temporarily which has com1/IRQ4
(nothing else will do) enabled and I wouldn't be surprised
if things work. The other thing you can try is a
communications program which allows you to specify the IRQ
it uses for the comports. Telix and Lync are two such
programs. You might have something like this so it would
be an easy test. You may have to plug in an external modem
for the test though.

There is no "COM" command in DOS. Atleast not in MS. You
could try fiddeling with the MODE command, that is a way
to initialize ports.

It just sounds like a simple conflict. What exactly did
you add?

What! No service technician flown in to make an
exact/company-sanctioned/hand-over-your-credit-card
replacement? This is a puzzle. Couldn't possibly work!
"I'm sorry sir, we cannot guarantee the comports unless
you pay us for a battery." <VBG>
