I am using a -current system with a USR 28.8 external. It answers the
line without any trouble.
Make sure you have the dip switches set to:
Or in English:
Verbal result codes
Suppress result codes
No echo, offline commands
Auto answer on first ring
Carrier detect normal
Load NVRAM defaults
Additionally, make sure you have done a "AT&F1" and "AT&W" to switch
on hardware flow control and save those settings.
One other thing... I haven't had any luck at any com port speed
setting other than 38400.
Here's my /etc/ttys entry:
tty00 "/usr/libexec/getty std.38400" unknown on rtscts
