# 'Fix' an USRobotics modem.
|
|
# This script writes a configuration suitable for operation with IRIX
|
|
# into the non-volatile memory in the modem.
|
|
|
|
# -i for inbound use only
|
|
# -o for outbound use only
|
|
# -io for both
|
|
# -m model to specify the model number, as in "-m 14.4ex"
|
|
# -v for verbose debugging
|
|
# -c cmd to add the string of Hayes-like commands, "cmd",
|
|
# to the end of string of initializations.
|
|
# -s bps to specify the DTE speed, either "19200" or "38400"
|
|
|
|
# This script must be run by "root".
|
|
|
|
# When this script is run, it sends the responses of the modem to
|
|
# standard out. It ends by telling the modem to display all
|
|
# of its parameters. If you do not see the right results,
|
|
# first check the cable to the modem.
|
|
|
|
# This script uses 'ttyd*' device names, so that it is not stopped by a
|
|
# need for DCD. Since there is often a getty(1M) running on
|
|
# a 'ttyf*', and since you cannot simultaneously open 'ttyf' and
|
|
# 'ttyd', it is necessary to stop the getty in /etc/inittab
|
|
# before using this script. If a uugetty(1M) is running on the
|
|
# port, it need not be turned off, because this script will
|
|
# temporarily disable it.
|
|
|
|
|
|
# Additional local commands should be added to this file in the following
|
|
# line or provided with the -c option
|
|
loc=""
|
|
|
|
|
|
# With a USRobotics Sportster or Courier,
|
|
# use a line in /etc/inittab that runs /usr/lib/uucp/uugetty with arguments
|
|
# such as the following:
|
|
# -Nt60 -iusrin,conn ttyf2 dx_38400
|
|
# See `man uugetty` and `man inittab`.
