Dear All,


The router's AUX port is configured as follows


line aux 0

exec-timeout 5 0

logging synchronous

login local

modem InOut

exec prompt timestamp

transport input all

flowcontrol hardware


An external dialup modem is connected to the AUX port of the router and modem is configured for Auto answer.


When i connect to the router through a PSTN dialup I dont get login propmt.


Please see the capture.


I have tested the modem by connecting to another router. The PSTN connected to the modem is fine since I get hand shake tone and can see connect at 9600 baud but dont get the login prompt.


what could be problem.


Regards,

Easwar

But after logging into the router I found that the aux line is always active even after resetting the modem what could be problem (the show line capture is as below)

router#sh line
