    i give up!!

    I have been trying to connect a summagraphics digitizing tablet to 
    a 4D/25G personal iris...

    i connected it to the second serial port  and
    tried to talk to it using the cu command .. this is what i got

    iris%cu -s 9600 -l /dev/ttyd2
    Connect failed: CAN'T ACCESS DEVICE
    iris%


    the table in "Devices" is o.k.  and uucp has permission 

    what else is there??  any help will be most appreciated....

    thanks.....

   On our 3130 the ports are labelled 1 thru 4, however, these correspond
to ttyd[0-3].  I don't know if SGI also misslabels the ports on the 4D
or not, but that could be the problem.  Also you might want to use ttyf?
they provide hardware handshaking.
