[comp.sys.sgi] Connecting a LaserWriter to a /dev/ttyf* serial port

elkins@topaz.rutgers.edu (George Elkins) (07/26/89)

Does anyone know the exact Iris 9-pin to LaserWriter 25-pin
connections for a ttyf[5,6,7,8,9,10] port?  (I am using the
6-port RS-232 option on an Iris 4D 120.)

It seems easy to get a LaserWriter working on a ttyd type of serial port
(since only three pins matter), but I would like to take advantage
of the flow control offered by those extra unused pins.

Is it currently possible at all to use more than the "Transmit Data",
"Recieve Data", and "Signal Ground" pins in these serial ports?

thanks,

George Elkins
