The last time I rebooted the computer on which mgetty runs was about half
a year ago and in that time I must have made at least a hundred calls from
my laptop with my 6110

A piece from my logfile from the start of the call:

kernel: isdn_net: Incoming call without OAD, assuming '0'
kernel: isdn_net: call from 0 -> 0 123456789 ignored
kernel: isdn_tty: Incoming call without OAD, assuming '0'
kernel: isdn_tty: call from 0, -> RING on ttyI8

The difference is in the second line with isdn_tty. In your case it states
"ignored", in my case it is recognized as a call on ttyI8. So this is the
point where things go wrong. It seems mgetty is not connected to your
ttyI1 device. I think you should have a look at your mgetty logfile, in my
case that is /var/log/mgetty.ttyI[linenumber].

An example from my mgetty.ttyI8 logfile:

I wonder how your logfile looks.

If I remember well, that is the message I wrote.

Hope this helps.
