To reset the hardware for one or more manageable modems on an access server or router, use the clear modem EXEC command.
clear modem {slot/port | all | group group-number | at-mode slot/port |
test }
slot/port Clear the modem at the specified slot and modem port number. Remember to include the forward slash (/) when entering this variable. For example: 1/1. This variable can also be used with the subcommands clear modem at-mode and clear modem counters.
all Clear all modems. This command disconnects any active calls.
group group-number Clears the modem hardware for a group of modems. The modem group-number is the number of the group you have previously created.
at-mode slot / port Tears down an AT directly connected session. The variable, slot/port-number, is required. This EXEC command clears an attention (AT) directly connected session to a manageable Microcom modem from a second Telnet session.
test Clears the log or test report that is displayed by the show modem testcommand. If you do not clear the test regularly, eventually the oldest test report will replace the current test report.

The modem hardware is reset for modems that are idle or busied out for long periods of time.
An AT directly connected session is usually initiated and closed from the same Telnet session by using the modem at-modecommand and Ctrl-C . However, you can clear an AT directly connected session that was mistakenly left open by enabling the clear modem at-mode command from a second Telnet session in to the access server.
The following example of the clear modem slot/port command resets the hardware for manageable
modem 1/1:
as5300# clear modem 1/1
The following is an example of using the clear modem all command:
as5300# clear modem all This command will disconnect any active calls. Clear (reset) all modems? [confirm] Clearing modems................................................ Done as5300#
The following examples of the clear modem group command clear the manageable modems in group 1:
clear modem group 1 clear modem group1
The following example executes the clear modem at-mode command from a Telnet session:
router# modem at-mode 1/1
The following example executes the clear modem at-mode command from a second Telnet session while the first Telnet session is connected to the modem:
router# clear modem at-mode 1/1 clear "modem at-mode" for modem 1/1 [confirm] router#
The following output is displayed in the first Telnet session after the modem is cleared by the second Telnet session:
Direct connect session cleared by vty0 (171.69.1.164)
| Command | Description |
|---|---|
| clear modem counters | Clears the statistical counters on one or more manageable modems on access servers or routers. |
| interface group-async | Creates a group interface that will serve as master, to which asynchronous interfaces can be associated as members. |
| modem at-mode | Opens a directly connected session and enters AT command mode, which is used for sending AT commands to Microcom manageable modems. |
