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.

Easwar

Your router does not have an enable secret password, so incoming connections will not be able to enter the enable mode.

thanks for your replies...
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)

Please try using "autoselect during-login" under line aux 0.
ubr10k2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ubr10k2(config)#line aux 0
ubr10k2(config-line)#autos
ubr10k2(config-line)#autoselect ?
arap Set line to allow ARAP autoselection
during-login Do autoselect at the Username/Password prompt
ppp Set line to allow PPP autoselection
slip Set line to allow SLIP autoselection
timeout Set wait timeout for initial autoselect byte
Thanks, Mak

Dear All,
Please find the capture of sh line and sh line 1 we can see that the modem inout is clearly shown. But in sh line 1 we can see that the modem hardware state is showing CSR* DSR* DTR RTS.
I am not getting router login prompt. I can see the modem ring and handshake.
Any suggestion how to resolve this issue.
Regards,
Easwar
