Thanks for you answer but i dont know how program these lines for control
ioperm(). Yes my system is Suse Linux 9.3 with kde upgraded 3.4.1
I solve the problem (in old wine) of this way:
In the old file config i write
"378" = "/dev/parport0"
"read" = "0x779,0x378-0x37f,0x280-0x2a0"
"write" = "0x779,0x378-0x37f,0x280-0x2a0"
I set the attributes
crw-rw-rw- 1 me root 99, 0 2005-03-19 16:36 /dev/parport0
crw-rw-rw- 1 lp lp 6, 0 2005-03-19 16:36 /dev/lp0
and add Myuser to the lp group.
With all this i get the right of access.
Maybe if you sendme a clue maybe i can make the wrapper.
