Hi all,
Being still new to linux and EMC2 I have decided to use an old computer to
learn more about it, using a small table top mill that I built using various
parts. Wanting to branch out into a cheap I/O upgrade I decided to purchase a
PCI parallel port card. But I have run into a problem getting this going.
After installing the card, I used "sudo lspci -v" to find out the address, this
is what was displayed:

Assuming that this "00:0b.0 Serial controller: Titan Electronics Inc VScom 010L
1 port parallel adaptor" was the pci card that I recently installed, I used the
address "c400" for the address in the .hal file line:
loadrt hal_parport cfg=0xc400
The .hal file that I used was created by stepconf, and functions fine with the
built in parallel port. But when I use 0xc400 as the address I get this error
on startup of Axis:
Debug file information:
insmod: error inserting
'/usr/realtime-2.6.24-16-rtai/modules/emc2/hal_parport.ko': -1 Device or
resource busy
FlatBed_Scanner_Mill_2nd_parallel_port_test.hal:27: exit value: 1
FlatBed_Scanner_Mill_2nd_parallel_port_test.hal:27: insmod failed, returned -1
See the output of 'dmesg' for more information.
4820
PID TTY STAT TIME COMMAND
Stopping realtime threads
Unloading hal components
And also from dmesg:
[ 336.998036] config string '0xc400'
[ 336.999790] PARPORT: ERROR: request_region(c400) failed
[ 336.999821] (make sure the kernel module 'parport' is unloaded)
I have tried the other three address's listed. They allow Axis to start but
cause no outputs on the parallel port card.
Also, after searching the Gmane archives, I found info about Netmos cards but
nno luck on VSCom.
I am sure that I missed some steps in the setup fo this card but am unsure as
to what they are.
What are the steps that I missed to do and what can I do to track them down?
Thanks,
Will Baden
