No possibility to change, as far as I can see. A little surprised though,
because the program works on Hercules and CGA screens, so there should be
some kind of selection mechanism. I suspect it is automatic.

I remember 'keyfake'. In fact, I wrote a TSR program that fakes
keypresses. I hadn't thought about PrtScr though. I believe there was an
interrupt called when PrtScr was pressed. But, I seem to remember
it prints directly, so I suspect it'll be easier to modify the TSR to
make it read the screen memory directly. 

Thanks for the suggestions!
