Create the following files and entries and I guarantee that 'cu' will work
for you. After you've created these files as below (note you may need to
modify the 'zoom dialer' for your modem) try 'cu nisttime'.
The attached are the configuration files for Taylor UUCP. Taylor UUCP
configuration files are defined quite well in the Linux Bible.
Note: /dev/cuaa1 should be used for outgoing calls and /dev/ttyd1 should
be used for incoming calls. /dev/ttyd1 should have a getty running
on it (getty is started by editing /etc/ttys).
I'm not sure how to set up a modem for both outgoing and incoming.
You may get permission denied from cu when trying to make an out-
going call on a port that has a getty running on it.
The dialer chat script below turns on auto answer each time you use it
though, ie: S0=2.
/etc/uucp/port:
# Build a port entry for all supported baud rates, only
# 9600 and 19200 are shown here. Supported baud rates
# are: 110, 134, 150, 300, 600, 1200, 2400, 4800, 9600
# 19200, 38400, 57600, 115200.
#
# The following is a port description for a 9600 baud
# outgoing call using the 'zoom' dialer. My modem is
# a zoom modem. The dialer can be any key word that
# points to an AT command set for your particular modem.

# This is the chat script I use called 'zoom'. It is for an

# This is an 'expect send' sequence. Use cu -d for debugging

Hope this helps.
