How to disconnect and logout from console session using modem

[yutashimamura2920]

Does anyone know how to logout and clear PSTN session when we login via US Robotics modem?

PC ---- US robotics modem ----PSTN line ----- US Robotics ------ C1111 Router

The above is the network diagramu.

I could login to C1111 router through the modem, but i dont know how to clear PSTN session.

I gave " exit" command, username/Password prompt is shown up again and again.

====================
C1111#exit

User Access Verification

Username:

====================

Also, "clear line 0" commad did not work.

====================

C1111#clear line 0
% Not allowed to clear current line [OK]
C1111#

====================

if you login via dialer, either kill the console session or clear dialer sessions to kill all sessions

What is the command for "kill the console session "?

Hello @yutashimamura2920 ,

the problem with the modem attached to the console line is that you cannot configure modem control on the console line and as long as the two modems are connected, you will always have access to the console line. The only possibility is to hangup the modem from the remote site.

Now, if you were to connect the modem to the AUX line, you can configure on this line modem control:

device(config-line)#modem dialin

this gives you the possibility to hangup the modem when you issue the clear line aux 0 command.

For a complete functional config you will also need the following line commands:

exec

databits 8

stopbits 1

parity none

speed 9600

Hi Guys!

Thank you for your comment!
I could log out by the command "+++" successfully!
Appreciate your support!

Re. I could log out by the command "+++" successfully!

The "+++" modem command switches the modem from data mode to command mode which causes the modem to drop the Data Terminal Ready (DTR) signal  which results in modem hangup.
