Synopsis

This family of commands is used to configure modems on TTY lines. The discussion is limited to commands that are available for all routers. Terminal servers with manageable modems, such as the AS5200, AS5300, and CS3600 series products, have additional commands.

modem answer-timeout time

Sets the amount of time the router waits for the carrier signal after answering an incoming RING.

modem autoconfigure discovery

The router automatically tries to discover the modem type.

modem autoconfigure type type

Sets the modem to the type known by the router. To view a list of known modems, use the command modem autoconfigure type?.

modem callin

Enables support of modems that use DTR to control hook-status.

modem callout

Enables reverse connections. (See Chapter 4.)

modem chat-script script-name

Specifies which chat script to use when the modem is automatically dialing. See Chapter 11 for more information.

modem cts-required

Configures a line to require the CTS (clear to send) signal.

modem dialin

Configures a modem to accept incoming calls only.

modem dtr-active

Configures the modem line to leave the DTR signal low unless there is an active connection.

modem inout

Allows both incoming and outgoing connections to the modem. This command enables reverse telnet, so be sure this what you want to do.
