I think, from memory, you need a VXD so that your program "captures" the port. There was some program/component called something like "TVich32" kicking around a while ago for this. Another trick that seems to work is to remove any printer associations via "My Computer". Win95/98 seems to leave the port alone then. Not likely to be practical and even less likely to be popular. In any case it should be possible to latch the the port externally by decoding a sequence of port writes (to distinguish from Win95/98 interference) as the timing for changing tones is pretty relaxed. 73s Steve
