Speaking of Windoze. W98 says I have COM2 and it is working.
Modem on COM5.
When I try to run a terminal program in DOS it says there is no

COM2

but it does see COM1. Checkit in DOS at first found COM1 and said
it was OK sans loop back. When I connected TX to RX ( 9 pin conn
pin2 to pin3 loop back) it said input register failed. When I run
checkit now it says no COM ports?????
Yet the terminal program still sees COM1. Nothing is working off
COM1. No GPS no data acq no echo in terminal program. Did I kill

it?

Just tried the GPS with another DOS computer on COM1 and the
GPS is working fine. Must be a bad com port on my IBM.

Paul are you running dos under windoz?

NO!

Microsoft windoz will change the interrupts to suit itself and com1

could end up being com5, com3 or whatever it

chooses. It does this in order to use a port for other cards, sound,

or

whatever you have installed.

You may want to ping com1 to see if it is still active.  Do you have

a

modem on com1, and are the manual

jumpers/switches set for com1, or is it a PNP?
If you are running in a dos box under windoz run the program in

straight

dos, boot with a dos floppy, or use the

F8 button at boot and choose command line prompt.
If your modem is physically connected to com1, windoz is probably

diverting the port to com?.

I was accessing in in QB  under DOS and a terminal program in DOS.

Paul Lamar

Paul, for what its worth.

I am running Windows 98 and my system can't find COM2.  I know it is

there

as I have a plug for it and my computer literature says its there AND I

used

it to upgrade the data base in my Garmin not too long ago - go figure.

Ed Anderson

OK all you computer gurus what is going on with silly Windows?
How do we fix this under DOS. Is there a location we can poke in
for the proper interrupt?

Paul Lamar

Do you have an IR port on your laptop?
If so then the IR port will probably be com2 in Win98

Erik

Yes I do. How do I delete it? I can't seem to get into the bios.
