My first tries with ISDN ;-)



I take the TA128 and connect it to the ttyR1 port, set in mgetty.conf:

port ttyR1
 debug 8
 init-chat "" \d\d\d+++\d\d\dAT&FS2=255 OK ATN3S0=0 OK
 statistics-chat "" AT OK ATI3 OK
 statistics-file /var/log/stat.ttyR1

and in the file /etc/ppp/options:
modem
crtscts
lock


in the file /etc/ppp/options.ttyR1
203.67.189.1:203.67.189.101


and finally in the inittab

s1:345:respawn:/usr/local/sbin/mgetty ttyR1 -D

telinit q

That is it!

Will it work? or have I forgotten something?

No, it did not!

The customer used the adapter and dialed up with different settings, he gets the login prompt, he typed in 
blind the login name, but nothing happens. There is no syslog, messages or debug entry only the 
stats.ttyR1:

As you can see, the customer tried with different protocols, but my system does not respond to him 
after his login prompt.


The log file of the mgetty shows me:

What does it complain about the ttyR1?


Is it a setting on my customers site or on my site that is missing?
