Parameters
None
Description
Use the modem auto-answer command to configure a modem to operate in auto-answer mode.
Use the undo modem auto-answer command to configure a modem to operate in non-auto-answer mode. Then, the modem answers a call only when it receives the AT command sent by the router.
By default, a modem operates in non-auto answer mode.
Use these two commands according to the actual answer mode of the modem. When the modem is in auto-answer mode (the AA LED of the modem lights up), use the modem auto-answer command to prevent the router from issuing answer instructions. If the modem is in non-auto answer mode, use the undo modem auto-answer command to enable the router to issue answer instructions on the arrival of incoming calls.

NOTE: · This command applies to only AUX ports. · If the answer mode configured is not consistent with the actual answer mode of the modem, the modem may operate improperly. Do not perform the operation unless absolutely needed. |
Examples
# Configure the modem connected to the asynchronous serial interface user-interface1 to operate in auto-answer mode.

service modem-callback
Syntax
service modem-callback
undo service modem-callback
View
System view
Default level
3: Manage level
Parameters
None
Description
Use the service modem-callback command to enable the callback function.
Use the undo service modem-callback command to disable the callback function.
By default, the callback function is disabled.
With the service modem-callback command executed, the modem initiates callback when the line is active (the modem detects the carrier or data is being received). As PPP process does not begin at this time, the callback is performed before accounting. Such a mechanism saves cost.
Examples
# Enable the callback function.
<Sysname> system-view
[Sysname] service modem-callback
