Usage guidelines
To ensure correct operation of the modem, set the auto-answer mode on the user line to be the same
as the modem.
• Enable auto-answer mode if the modem is in auto-answer mode (the AA LED of the modem
lights up). This setting prevents the router from issuing a duplicate answer command after the
modem answers a call.
• Disable auto-answer mode if the modem is not in auto-answer mode.
This command is available on the following user lines:
• TTY lines for the following interfaces:
AM interface
Asynchronous serial interface
Asynchronous/synchronous serial interface operating in asynchronous mode
• AUX line
This command is not available on the console or VTY lines.
To display the user line for an interface, use the display line command.
Examples
# Enable auto-answer mode on TTY 1.
<Sysname> system-view
[Sysname] line tty 1
[Sysname-line-tty1] modem auto-answer
