This took a while, which is why I have been so tardy.

As a general observation an old VT220 and an RS232 tester with flashing
lights are invaluable for this serial port stuff.
GTCO Digipad 5A on serial port B
(i) The serial ports on the SPARCstation are set to RS423 by default,
you can use jumpers in the pizza-box to set them to RS232.
(ii) Make sure the switch settings are correct on the digitizer
S3 S2 S1
on x xxxxx xx x x
off xxxx xxx xxx xx x x
(thanks Eric for the right settings)
(iii) If you are using port J5 use a null modem cable to connect to the
serial port( to get the connections right)
(iv)Use admintool or pmadm to set ttyb to 9600
and Software Carrier (!!!)
this last part seems very counter-intuitive and contrary to accepted wisdom
but its what I had to do to get the $%#@ thing to work.
(v) make the actual device file
readable by everyone.
You can test if you've got it going by issuing the
digtest gtco16 /dev/ttyb:9600:8bit:none
command in ARC/Info
