Mode
The format in which the data flows back and forth.
With
Text
selected, the SLC assumes that the modem will
be used for remotely logging into the command line. Text
mode is only for dialing in. This is the default.
PPP
establishes an IP-based link over the modem. PPP
connections can be used in dial-out mode (e.g., the SLC
connects to an external network) or dial-in mode (e.g., the
external computer connects to the network that the SLC is
part of) or dial-on-demand. For ISDN cards, only PPP
connections are allowed.
Initialization Script
Commands sent to configure the modem may have up to
100 characters. Consult your modem’s documentation for
recommended initialization options. If you do not specify
an initialization script, the SLC uses a uses a default
initialization string of
AT S7=45 SO=0 L1 V1 X4 &D2
&c1 E1 Q0
.
Note:
We recommend that the modem initialization script
always be preceded with AT and include E1 V1 x4 Q0 so
that the SLC may properly control the modem.
Caller ID
Logging
Select to enable the SLC to log caller IDs on incoming
calls.
Note:
For the Caller ID AT command, refer to the modem
user guide

Text Mode
Timeout
Logins
If you selected
Text
mode, you can enable logins to time
out after the connection is inactive for a specified number
of minutes. The default is
No
. This setting only applies to
text mode connections.
PPP
mode connections stay
connected until either side drops the connection. Disabled
by default.
Dial-back Number
Users with dial-back access can dial into the SLC and
enter their login and password. (See
Setting up Local
Users
on page 94.) Once the SLC authenticates them, the
modem hangs up and dials them back.
Select the phone number the modem dials back on: a fixed
number or a number associated with their login. If you
select
Fixed Number
, enter the number (in the format
2123456789).
