Modem Option Settings
Issue 2 December 1996
B-15
There are three jumper pins (labeled JP1 ) on the left side of the circuit board.
When the jumper plug connects the left and middle pins (as shown in the figure),
the modem is in the noncommand ( dumb ) mode. When the jumper plug
connects the right and middle pins, the modem is in the command mode (the
factory setting). To change the jumper setting, lift the plug up until it clears the
pins (the plug may have to be tilted outward to clear the top of the housing); then
slide the plug down on the middle pin and the other end pin. Replace the
endcap, reconnect the telephone wire and computer cable, and plug in the
power cord.
For more details on setting options for the Lucent 2400 modem, see the booklet
that is packaged with the modem.

when this modem is connected to DEFINITY AUDIX. Enter AT to get the OK prompt, then
enter the following string:

This command sets maximum rate to 9600, writes this setting to modem profile 0, and locks
out the escape character.
