(Fwd) [Tech] due modem :-(( ???
Su una macchina avevo (e ho ancora) un modem , interno V34 su ttyS2
e faceva il dialin correttamente (e continua a farlo ...)
Ci ho montato su ttyS1 un TA esterno ISDN e configurato come segue
(porzione di inittab)
# /etc/inittab: init(8) configuration.
# $Id: inittab,v 1.8 1998/05/10 10:37:50 miquels Exp $
# Format:
# <id>:<runlevels>:<action>:<process>
1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2
3:23:respawn:/sbin/getty 38400 tty3
4:23:respawn:/sbin/getty 38400 tty4
5:23:respawn:/sbin/getty 38400 tty5
6:23:respawn:/sbin/getty 38400 tty6
# Example how to put a getty on a modem line.
T3:23:respawn:/sbin/mgetty -x3 -s 57600 ttyS2
> T2:2345:respawn:/sbin/mgetty -x9 -D
-m '"" ATZ OK AT&ZI2=554627468**6 OK' -s 115200 ttyS1
(la ultima riga e`spezzata per migliorare la vostra leggibilita)
Dopo questa modifica la linea su ttyS2 funziona regolarmente
mentre la linea su ttyS1 non va ... mi spiego:\
se entro con un terminale mi arriva il prompt login, do a mano il login e
tutto precede come se avessi una sessione su una consolle seriale ....
se invece attivo il ppp dopo lo scambio di password e login mi esce di
brutto.
che ho sbagliato ?
dalla stessa macchina ho provato a collegarmi (ovviamente con modem
diversi) e funziona (in V34) ...
ecco il log:
