[comp.sys.apple] Serial Ports on the GS they work like Super Serial

delaney@wnre.aecl.CDN.UUCP (06/03/87)

Well despite an earlier message the GS serial port does emulate a Super
Serial card (wish apple would put the commands in the manual).  I borrowed
a manual and sure enough IN#2 followed by carrage return gave a flashing
? when a control A was typed.  As the letter said a Ctr A 3B gave 300 baud
and Ctr AT resulted in an underline cursor.  This indicated I was in terminal
mode so a few AT commands to my modem and I was on the system.  I'm using
it to send this.  So if your listening to us little people apple tell us
what our machines can really do.  All commands I tried seem to work although
the desk top does not indicate any changes were made and the system reverts 
to the desk top settings.  By the way to go from 80 column to 40 column you
old ][+ ers you use ESC ctrQ not pr#0 as back in the old days.
Hope this a bit of help.
