How do I hook up a terminal to the IIgs printer/modem port? A#8.9: This answer describes hooking up a terminal to the printer port.
Hooking one up to the modem port will be similar except that .ttya should be used instead of .ttyb. On the hardware side, you will need a mini DIN 8 to DB25 printer cable. This should be connected from the IIgs’ printer port to the port on the terminal that would normally be hooked to a modem. Next, you have to run a getty(8) over the printer port. Add this line to your /etc/inittab file: pp:23478:rest::/usr/sbin/getty 8bit.xxxx .ttyb where xxxx is the speed. Remove ’78’ from ‘23478’ if you want to run it only in multiuser mode. See also Q#8.8 regarding initialization of the serial port. In order for the change to take effect, you either have to quit and restart GNO, or type ‘/bin/init q’ (without the quotes).
