System: SUN 3 (/50 and /180) running SUN OSv3.5 (still!) Problem: 1200/2400 baud rotary settings don't work Also: Any nifty solutions to dial-in *and* dial-out on the same port? Full description: Getty doesn't seem to work properly using the 1200/2400 rotary entries; that is, auto-switching 1200<-->2400 as described in the default /etc/gettytab. The first problem is that the port is always left at the speed selected by the last user and never defaults to the selected item specified in /etc/ttys. Second, although the speed can be successfully changed by a BREAK from a 1200 baud modem (2400 -> 1200 on the port), there is no way to get the break signal to work properly when sent from a 2400 baud modem (1200 -> 2400 on the port). Therefore, any 1200 baud user can access any port in either of its states, but a 2400 baud owner has to hope the getty is already listening at 2400, since his break signal will never flip the line to 2400. Here are the relevant parts of /etc/gettytab. /etc/ttys was defaulted to 3 on the proper tty(s). F|std.1200S|1200-baudS:fd#1:sp#1200:lm=: G|std.2400S|2400-baudS:sp#2400:ht:lm=: # Fast dialup terminals, 1200/2400 rotary (can start either way) # 5|D1200|Fast-Dial-1200:nx=D2400:tc=1200-baudS:lm=: 3|D2400|Fast-Dial-2400:nx=D1200:tc=2400-baudS:lm=: # The break signal is a hardware one, can it be due to the datacards of the terminal server? Does anyone else ever tried 1200/2400 rotary tables on this OS? Is there a simple patch? Also, has anyone worked a nifty way to have dial-in *and* dial-out on the same modem line? As many know, dialing out on a port occupied by a getty process is not feasible.
