Help Needed with DOS program under Windows XP

I have an old DOS program called Symate Plus (Square D) for coding PLCs.
(It dates from about 1993.)
On one computer running XP Professional it runs fine, either in a window or full screen.
On my other computer running XP Home it starts okay but the ten function keys won't work. (The program is accessed via the function keys.)
I've tried everything I can think of to get it working on my other computer but without luck.

Can anyone help with this?

1. Did you try all options?
2. Convert from XP Home to XP Professional on your 'other' machine. It's a superset, so you shouldn't lose functionality.
3. Try Vista
4. Contact Symate Plus customer support
5. Go and buy a XP compatible program for coding PLC's. DOS support is fading away.
6. Any second hand machine able to run DOS 6.0/Windows 3.1 should suffice. They are very CHEAP. Buy a KVM-switch so you can share keyboard, mouse and monitor. The box the program runs on isn't important at all; the user interface should be all that matters.

Hope this helps.


PS. Maybe someone else can help you to get this running on XP Home. Sorry, but I can't.

DOS Compatibility issues under Windows XP

In reply to: Suggestions.

Thanks for the prompt reply.
I have tried Googling - obviously not a common problem.
Since it runs on one computer and inexplicably does'nt run on the other I am thinking it's a minor software difference. Perhaps a different driver that clashing or even a keyboard driver that's stopping it.
Might even be a software switch I haven't come across.
I have of course looked at the DOS compatibility switches in the MSDOS properties tag on the desktop icon. There are a lot of switches for DOS memory etc but nothing that seems relevant to the keyboard.
These are all at their defaults on both computers.

Keyboard Scan Codes

In reply to: Help Needed with DOS program under Windows XP

If you are still trying, this link to an article on remapping keyboard scan codes in XP may help?

XP changed some of the keyboard scancodes in the registry.
Hopefully, the DOS program you are using, doesn't contain it's own
hooks via DOS to get the scancodes from the system. If the program worked with other windows programs, investigating how the scancodes
changed with XP may help you to remap your way to using the function keys again...oh yea... the link is below; (hope it works).,1895,1561005,00.asp
