Actually, Bob, you and Dave are talking about two different things. You 
were describing the dlportio dll (port95nt.exe is an installer program for 
dlportio) that can be installed on Windows XP computers to get access to 
the DTR/RTS lines on serial ports and to any of the signal lines on 
parallel ports.

What Dave was talking about was the EXTFSK dll from JE3HHT - you can find 
it in file comfsk105.zip at the MMTTY web site. Instead of the normal TxD 
line, EXTFSK allows you to output the FSK keying signal on DTR or RTS from 
a serial port, or on a data or strobe line on a parallel port. If you are 
running XP, you need to have dlportio installed as well. So far, I have 
been able to make it work on DTR from a real serial port. I have not yet 
got it working from a generic (non-Belkin) USB adapter, because MMTTY 
doesn't seem to see that port. I have been able to toggle DTR on that 
adapter from another software program, so by all rights it ought to be 
possible, but... I haven't wired up a parallel port interface to try that yet.
