Description
Use the modem auto-answer command to have the external modem connected to the
asynchronous interface automatically answer or hook off.
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 instruction 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
instruction after the modem answers automatically. If the modem is in non-auto answer
mode, configure the undo modem auto-answer command.
