According help
cw keying is on pin 1 and pin 17
ptt 16 and 18 (only used when a ptt delay value exists)
Radio 2 is on pin 14 and pin 18
So it should work.
Sorry i have not tested an Lpt port.
Have you run the lptdriver.exe?
It is in dx4w805>drivers directory.
Also under file>preferences>control there is a box called reverse 1/2. It is 
for changing radios but like an idea check and uncheck this also. Maybe a 
bug there? Just thoughts....
