Hi Paul,

The other way is to upgrade to Windows 2000, When you up grade you don,t lose any information and you can convert to NTFS at

the

same time. With Windows 2000 you can have as many partitions as you want, also you can run one with Linux.
I use Windows 2000 and have another partition with a second copy incase the first gets a virus. I just delete the infected partition

and

use

the next one.
Regards Don

The big problem is, as Aden pointed out, Windows is not at all suited to real
time stuff. Anybody got an old DOS running notebook computer in
good condition they want to sell?

Hi Paul,

You can also have a DOS partition with 2000

Well that might be the answer. Partition and then install 6.22
instead of what ever weird version of DOS that comes with 95 and 98.
Perhaps then I can get real control over the serial ports.

Paul 7.0 DOS and the 7.? with win95, 98 is an expanded version of ver 6x.
We have never had any compatability problems with using it .
We have not used any other version for several years, and it runs all our dos software without a hitch.  You never know that it is ver 7x. So
weird doesn't mean anything to us.  Why do you consider it weird?

Both Ed and I are having problems accessing the serial ports while
in DOS (7.x?). Ed is running 95 and I am running 98. I can send you a GPS
simulator designed to out put GPS data continuously just like a real
GPS and you can run that in an old DOS computer and hook it to the 
RS232 on a notebook running 95 or 98 DOS and see the problem for yourself. 
Here is a short program that reads the GPS data coming
in from a serial port and records the arrival time down to a millisecond.
This program works fine with data from a real GPS and an old DOS 5.0
computer.
