What device is open on handles f3 and f4?  If that is the terminal (as it 
seems it is), you could try simply commenting out this code, I don't 
think it's needed with DJGPP.

OTOH, if the device is not a terminal, but e.g. an async communication 
port, then this code will not work with DJGPP at all.
