[Dx4win] CW keying on XP thru LPT3

[Paul Ferguson]

I have a new Windows XP system. I installed a SIIG Cyber PCI I/O card 
to give me an extra LPT and two extra COM ports. 

The additional LPT port is LPT3. When I configure DX4WIN (Version 
6.02) to send CW over LPT3, DX4WIN says "Cannot find LPT3 for 
keying."

I see that LPT3 is installed by looking at the Device Manager ports. 
I also tried attaching a spare printer (an HP laserjet 5L)  to LPT3. 
Windows XP added the printer and it prints OK.

What does DX4WIN need to find LPT3?
