digitizer settings

Hi,
I am trying to set up our Calcomp 9500 digitizer with the settings I received
from Ken Sibley. The digitizer I will be using is used being used by Arc-Info
users. I understand that it is possible to save a set of parameters, and that
the parameters used by arc-info are different than the ones for GRASS. The
problem I face is that the template was removed from the digitizer. How do I
"tell the digitizer" where the template is? It would be nice if I did not
override the Arc-info parameters in the process. Also how do I save the GRASS
settings to recall them when I start digitizing.

Thanks for any help. Kathy

Kathy,
We use the following script to configure our Altek AC31 digitizer controller
for use with three different software packages (GRASS, Arc/Info, PCI). Perhaps
you can modify it to suit your requirements.
