Here is a script that may help some of you other Altek users. Instead of having
to manually set the dip switches, you can simply run this script to configure
the digitizer. Ravi Kiran, one of our system administrators, wrote this in
order to enable us to easily switch from digitizing in GRASS to ArcInfo to PCI.
It can easily be edited to suit your needs.
