492 CHAPTER 29: MODEM CONFIGURATION COMMANDS
Use the undo modem auto-answer command to disable the connected
external modem to answer automatically. In this case, the modem answers only
when receiving an AT command sent by software.
By default, the connected external modem is set to non-auto answer mode.
Use this command depending on the answer state of the connected external
modem. When the modem is in auto-answer mode (AA LED of the modem lights),
configure the modem auto-answer command to prevent the router from
sending an answer command after the modem answers automatically. If the
modem is in non-auto answer mode, configure the undo modem auto-answer
command.
n
If the configuration of this command is not consistent with the current answer
state of the connected modem, anomalies may occur. You are not encouraged to
configure this command.
