Clearing a Direct Connect Session on a Microcom Modem
The examples in this section are for Microcom modems.
The following example shows how to execute the modem at-mode command from a Telnet session:
Router# modem at-mode 1/1
The following example shows how to execute 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] <press Return>
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 (172.19.1.164)
Displaying Local Disconnect Reasons
To find out why a modem ended its connection or why a modem is not operating at peak performance,
use the show modem call-stats [slot] EXEC command.
Disconnect reasons are described using four hexadecimal digits. The three lower-order digits can be used
to identify the disconnect reason. The high-order digit generally indicates the type of disconnect reason
or the time at which the disconnect occurred. For detailed information on the meaning of hexadecimal
values for MICA modem disconnects, refer to the TAC Tech Notes document, MICA Modem States and
Disconnect Reasons, at the following URL: http://www.cisco.com/warp/public/76/mica-states-drs.html
For detailed information on the meaning of hexadecimal values for NextPort modem disconnects, refer
