[WT-support] Configuring LPT and DX Doubler

[Winfried Kriegl DK9IP]

Bruce,

in order to get your DX doubler working with modern PC/notebook hardware you might try to 
use something like that: 
http://www-user.tu-chemnitz.de/~heha/bastelecke/Rund%20um%20den%20PC/USB2LPT/
(page in german sri). A microcontroller is used to emulate a "real" LPT port. No guarantee 
that it will work without problems though.
