Hello,
Kernel 2.4.x (x=>9) should support a pcmcia parallel port. I have a
Qautech spp-100 pcmcia parallel port and I can not get it to work with
linux.
I have added a few lines to the parport_pc.c code and enabled the
#define DEBUG stuff to check what goes wrong. It appears that the
check_region() function fails the second time it is executed (see
attachment).
Can anyone tell me if the parport_cs code in the 2.4 kernel series is
known to work (and if so who uses it).
Or is it something I do when the pcmcia parallel port is initiated?
Thanks in advance
