OS456 serial port question

OS456 serial port question

Post by David May » Sun, 09 Jun 1996 04:00:00

I have an OS456 with a Realistic 2006 scanner.  I would like to use my
serial mouse, modem, and OS456 all at the same time.  (Greedy aren't I?)
I am running under Windows 95.  As you might guess I am fresh out of
serial interrupts after the mouse and modem.  My serial ports are on the
motherboard and seem to be fixed at IRQ3&4.  My modem is capable of
IRQ2/3/4/5/7, but I've only had luck with IRQ3 or 4.  Two questions:

1. Can I persuade Windows 95 to let me use IRQ7 for the modem?  This
should be ok as IRQ7 is the printer and it should be sharable as long as
I don't print while using the modem.  I have looked at the Control Panel
and it doesn't seem to have standard setups for com ports other than
IRQ3/4.

2. Is there a non-standard serial card available anywhere which doesn't
use IRQ3/4?  It would have to be recognizable by my ScanStar for
Windows SE software and Windows 95.

Thanks.

How about using a "bus" mouse - i.e. a PS2 mouse that comes with its own card, uses its own interrupt, and
leaves you with two workable com ports.  I have been using that system for several years, and have both com
ports usable.

Sealevel Systems (864-843-4343) makes a card called the DUOCOM (Part #3088)
that allows IRQ settings of 2-5, 7, 10-12 and 15.  I've got a HF receiver and
a 2006 with the Opto board sharing COM1 via a switch box, a TNC on COM2, a
modem on COM3 and COM4 is free.  Having a PS/2 mouse is a definite advantage.

yes - or have your sound card and your printer port share the same
interrupt (irq7) and then try using irq5 for the modem......

a couple of companies make a 16550 serial card that has high interrupt
capabilities.....you can choose any interrupt that is available for
either com port - and set them as com 1/3 and com 2/4.

Or as the other fellow said - you could try a bus mouse.

: 1. Can I persuade Windows 95 to let me use IRQ7 for the modem?  This

What is wrong with using IRQ5?  On many systems, it's open.  If you have
a soundcard there, you can probably move it to IRQ10.  I'd choose it
before IRQ7.

Try Control Panel, System, System Properties, Device Manager, this will
get you to a menu where you can diddle with the device settings.  I
myself can't try it now because I want to stay logged on, but it looks
this will let you set IRQ's of your choice.

If this fails, try visiting the "local library" (bookstore or book section
of computer store, that is).  Try first with the Win95 Resource Kit, a big
fat book written by Microsoft.  If you can't find it in there, there will
be tons of other books to try.  Buying the book(s) optional.

: 2. Is there a non-standard serial card available anywhere which doesn't

Likely so.  Any good computer dealer should be able to answer that.  If
they aren't smart enough to, try another dealer.

Also, as a last resort you could get a PS/2 type mouse and card, plug
that card in, and it uses irq12 and won't take up a com port.
