This should just work - at least I had another two Siemens phones work
with some Notebooks and NetBSD until very recently.

Hm. Try to use the non-DCD device, /dev/dty00, instead.

the modem is in command mode.
crtscts should be ok; combine with (no)modem and maybe (no)local.

some file using appropriate syslog.conf settings.
