wine users - May 2001 - how to use bidirectionnal parallel port?

Hi,

I'm trying to use an old win31 app for controling some data acquisition
board. The board is connected to the PC trough the parallel port.

I can print from Linux on this port.

the parallel port is on 0x3f8 irq 7  

I add 

  [parallelports]
  "Lpt1" = "/dev/lp0"
  
  [ports] 
  "read" = "0x3f8"
  "write" = "0x3f8"

to ~/.wine/config

As specified in the manual I'm running one of the needed apps as root in
order to access to the port. But wine freeze reporting in the console

  err:ntdll:RtlpWaitForCriticalSection Critical Section 0x400f1c48 wait
timed out, retrying (60 sec) fs=0267

a couple of time before exiting. And with the other app, it is the app
itself who respond "printer error".

I'have tried to find a maximum of info, faq, comments,... for more than
a week to no extend ;-/

any clues?

Success with 3.1 printer depends on several things:
- Wine can't use *.sys file ( to my knowledge)
- Direct port access is only possible when running wine as root
- Probably you need to allow the whole range of the parallel port 
  (0x378-0x37f)
- Be sure that the programm is configured to use that port
- Runn with --debugmsg +int what ports you program tries to access
  directly.

Hope this helps

Since the first PC appeared, all of them have a RS232  port at
this address. IIRC parallel ports are most often at 378 or 278.
