Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

more googling turned up a snippet about parport.opts for multiple cards, I don't have multiple cardss but here is my translation of that page:
case "$ADDRESS" in
# Options for card in socket 0
# Options for 'tunelp'
# Card eject policy options
also had to recompile kernel to include parport, parport_pc (IBM style), parport_cs (cs=card services?) module support. those were listed as required. thats 'M' for ALL the parport options in 22.214.171.124, apparently the modular setup is required.
so dmesg seems to now also recognize the card, and I made a symbolic link to the pcmcia 'card':
It'd be great help if anyone has time to peruse the above and poke any holes in it they might find. I have only 1 parallel port peripheral which has to be run from either DOSEMU or WINE which really confounds the debugging process here..
pls remember I'm a n00b at this and any scrutiny is appreciated. I'll of course keep plugging at this and sorry if my rambling is wasting space/time on the continuum..
you are correct, and I've been reading through the man pages about this but I'm not sure how to translate my card to the parport0 device node.
I have since done more tweaking, and now my kernel added ppdev (under char devices) which if I modprobe ppdev gives me a /dev/parport0 but I think thats still incorrect, because its not pointing to the pcmcia card.
the udev.rules is confusing the hell out of me..
i can't get wine to work with the parport either...
so I am now trying to get this up and working in dosemu (1.3.4, with free-dos) and added the line:
$_ports = $_ports, "device /sys/bus/pcmcia/devices/0.0 fast range 0x378 0x37f" # lpt0
which doesn't work... i'm searching for dosemu.conf syntax now..
$_ports = $_ports, "0x2100 fast range 0x378 0x37f" # lpt0
i get no detection from dosemu @ 0x378 though...
also of note, in windows the little light on my peripheral will glow red when plugged into the port, but now in linux it is not on... does this mean my port is not really 'on' or just that windows is sloppy about handing out power?
so now i'm trying to test from the linux side
#define base 0x378 /* printer port base address */
#define value 255 /* numeric value to send to printer port */
main(int argc, char **argv)
fprintf(stderr, "Couldn't get the port at %x\n", base), exit(1);
old snippet of a progr I found, but evervalue I can think to try as base returns 'couldnt get the port'
so the way the drivers work, please anyone correct me if I'm misrepresenting here, the parport is the top level driver and handles stuff to the kernel direct, parport_cs gets & passes information via parport_pc to create the pcmcia device. At this point one could use the address found by:
which finally let me cpu talk with the cardbus. the basic idea is there must be direct path between 00 and 02 (i'm kind of guessing here) else we better create on at boot time. another way to check for this need was/is dmesg | grep assign. if you see the kernel recommending it, go for it..
but lets just say... hypothetically, you need to use dosemu to write to an eprom burner, or eprom emulator...
enter ppdev... ppdev creates /dev/parport0 so that in /etc/dosemu.conf you can do this:
