Managing Modems
This section describes how to manage modems by checking the type of modem connected to the
access server, removing inoperable modems from service, and disabling a modem from dial-up
service. For details on disabling a modem from dial-up services, see the section, "Troubleshooting
Modems," later in this appendix.
Check Modem Type
To check the type of modem connected to the access server and to configure the modem
automatically, enter the following command in global configuration mode [the prompt is displayed

The modem is identified each time the line is reset. If a modem cannot be detected, the line continues
retrying for 10 seconds. When the modem type is determined, this information remains stored until
the modem is recycled or disconnected. Discovery mode is much slower than configuring a line
directly.
Each time the modem is reset (every time a chat reset script is executed), a string of commands is
sent to the modem, the first one being "return to factory-defaults."
Set Modem Event Buffer
This section applies to Microcom modems only. To configure the size of the history event queue
buffer for manageable modems in the access server, enter the following command in global
configuration mode [the prompt is displayed as
