[Linuxwacom-discuss] Serial Device Initialization on Compaq TC1000

[Christian R. <chr...@ne...>]

Hi, 
I spent quite a while trying to find out how to get the tablet stuff working 
on a Compaq TC1000. Amongst other stuff I came about the linuxwacom site and 
found the Documentation about Tablet PCs promising. 

I have the impression that I am stuck at initializing the serial device 
(connecting the tablet hardware to it). As mentioned in the documentation, 
chapter 7,  this has to be initialized on some Compaq Tablet PCs. There is a 
small c application meant to do this, but it is written for a compaq TC1100, 
a slightly newer model. It is also mentioned that this application has not 
been tested with the TC1000. I would like to do that, but I have no idea 
about kernel hacking and hardware stuff. So maybe someone can give me a 
helping hand? 

Thanks for any reply, I'll be happy to provide additional info !

This is the setup so far: 
Distribution: opensuse-10.2

I have the tc1000ts.c file compiled with -O2 and call it 
from /etc/init.d/boot.local: 

# some comments
touch /var/lock/subsys/local
/usr/sbin/tc1000ts
/bin/setserial /dev/ttyS2 autoconfig

boot.local IS processed, I can generate errors or logging from it. 

Nevertheless a setserial call afterwards still gives: 
# setserial /dev/ttyS2
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4

Consequently wacdump does not work:
# wacdump /dev/ttyS2
WacomOpenTablet: Invallid argument 
I also tried to use setserial by hand (without autofconfig), but could not 
produce any result.
