Re: allow access to parallel port

[Razvan Cosma <razvan.cosma@telemach.com>]

Status update: I gave up on the direct port access, and configured CUPS. 
I can print just fine from Linux, and can also do a echo "sdcsc" > LPT1: 
in dosemu.
But the application (which does a set output to printer or however that 
was called in dbase) freezes when trying to print. Listing the 
information on the screen works though. Is there anything special about 
the dbase/fox stuff?
