Nightmare on Digitiser Street

[David Houlder]

Right, this is driving me out of my mind...

I am trying to set up a Summasketch digitiser on a Sun IPX (SunOS 4.1.3)  to use with v.digit (grass 4.1, release 3). Shouldn't be too difficult, after all, I have the manual for the digitiser, and it says
	baud rate 	9600
	data bits	8
	parity bit 	odd
	stop bits 	1
Great! All the info I need. 

 So, I hop into the editor and set up digcap like this...

----
Summasketch:/dev/ttyb:ss3fmm_4:Summasketch III digitiser
----
... and there is no getty or lpd using ttyb.
Then I create ..../etc/digitizers/ss3fmm_4 like this...

----
# Summasketch III MM format

setup
{
    digname = Summasketch
    baud = 9600
    units_per_inch = 1000
    stop_bits = 1
    data_bits = 8
    parity = odd
}
