Configuring Autoselect

Autoselect is used by the access server to sense the protocol being
received on an incoming line and to launch the appropriate protocol.
Autoselect can be used for AppleTalk Remote Access (ARA), PPP, or SLIP.

When using Autoselect, "login" authentication is bypassed, so if security
is required, it must be performed at the protocol level, that is, the
AppleTalk Remote Access Protocol (ARAP) or PPP authentication. SLIP does
not offer protocol layer authentication.

To configure the Cisco IOS software to allow an ARA, PPP, or SLIP session
to start automatically, use the following command in line configuration
mode:

Command
Purpose

Router(config-line)# *autoselect *{*arap *|* ppp *|*slip *|* during login*}

Configures a line to automatically start an ARA, PPP, or SLIP session.

The *autoselect* command enables the Cisco IOS software to start a process
automatically when a start character is received.

The *autoselect* command bypasses the login prompt and enables the
specified session to begin automatically. However, when the*autoselect* command
is entered with the *during login* keyword, the username or password prompt
appears without the need to press the Return key; thus "login" users will
get a prompt right away without needing to press the Return key. While the
username or password prompt is displayed, you can choose either to answer
these prompts or to send packets from an autoselected protocol.

Normally a router avoids line and modem noise by clearing the initial data
received within the first one or two seconds. However, when the autoselect
PPP feature is configured, the router flushes characters initially received
and then waits for more traffic. This flush causes timeout problems with
applications that send only one carriage return. To ensure that the input
data sent by a modem or other asynchronous device is not lost after line
activation, enter the *flush-at-activation* line configuration command.
------------------------------

*Note *When the *autoselect* command is used, the activation character
should be set to the default Return, and exec-character-bits should be set
to 7. If you change these defaults, the application cannot recognize the
activation request.
------------------------------

See the "High-Density Dial-In Solution Using Autoselect and EXEC Control
Example"<http://www.cisco.com/en/US/docs/ios/dial/configuration/guide/dia_cfg_asyn_lns_int_ps6441_TSD_Products_Configuration_Guide_Chapter.html#wp1009054>

for an example that makes use of the autoselect feature.
