So the keyboard driver works in the Virtual DOS Machine (VDM) but it is still
occupied by the P&E program.

I am not an expert, but it seems you are right.

I just tried to research the problem and the first link on
http://www.pemicro.com/software/index.cfm
leads to
http://10.0.0.8/getting_started/dev_and_debug/flash_programming.cfm
So that does speak for itself.
Googling the problem brought two things:
This site says you could delete the keyboard controller from the device manager:

And this page suggests to use a ps/2 keyboard:

Both answers do not sound exactly right for the problem...
Maybe someone else here has an idea how to completely unload the previous
program.
