Hi, Kathy
If you look under $GISBASE/etc/digitizers, you'll see that the driver files are
ascii, and have a little bit of header info in each one:

124%>>more cc95f23_16

# Calcomp 9500  Binary format 23
#
# Originally build and tested by 
#  Terry Baker and David Gerdes  USA-CERL  1992
 
setup
{
    digname = Calcomp
    description = Calcomp digitizer, binary format 23
    buttonoffset = 1
    buttonstart = 0
    buttons = 16
    baud = 9600
    units_per_inch = 1000
    stop_bits = 1
    data_bits = 8
    parity  = none
}

(lines deleted)

Hopefully your digitizer manual should shed some light on what "binary format
23" really is!

Hope this helps,
