Writing to the lpt0 port.

[Fredrik Carlsson <fredrik.c@bigfoot.com>]

Hello, 

I have a LCD display 20x4 rows connected to my lpt port, and i'm now trying 
to write a simpel program to use it, i now that the display is working 
because i tried it in windows. But when i open a file pointer to /dev/lpt0 
and try to write to i i just get device busy ( ioctl(); ). I'm a newbie when 
it comes to c programming so i wonder if somewone has a tips or some nice 
info on how to write to lpt ports :-) 

please reply to my email adress, i'm not subscribed to the list.
