Troubleshooting Dialin Connections 16-355
Dialin: Dialin Client Receives No exec Prompt
Dialin: Dialin Client Receives No exec Prompt
Symptom: A remote dialin client opens a session and appears to be connected, but the user does not
receive an exec prompt (for example, a Username or Router> prompt).
Table 16-6 outlines the problems that might cause this symptom and describes solutions to those
problems.

Chat script problem
Step 1 Enter the debug chat privileged exec command. If you see the output
“Success” at the end of the chat script, the chat script completed successfully.
Step 2 Make the timeout in the chat script longer at the point where it fails.
Step 3 If the problem persists, verify that the command response to each chat script
step is correct. Open a reverse Telnet session to the modem and step through
the chat script.
Step 4 Fix any inconsistencies you find in the chat script.
For detailed information about creating and configuring chat scripts, refer to the
Cisco IOS Access Services Configuration Guide and Access Services Command
Reference.
1 Tx = transmit
2 Rx = receive
Possible Causes Suggested Actions
Autoselect is enabled on the line Attempt to access exec mode by issuing a carriage return.
Line is configured with the no exec
command
Step 1 Use the show line exec command to view the status of the
appropriate line.
Check the Capabilities field to see whether it says “exec suppressed.”
If this is the case, the no exec line configuration command is
enabled.
Step 2 Configure the exec line configuration command on the line to allow
exec sessions to be initiated. This command has no arguments or
keywords.
Example:
The following example turns on the exec on line 7:
line 7
exec
Flow control is not enabled, is
enabled only on one device (either
DTE or DCE), or is misconfigured
Step 1 Use the show line aux-line-number exec command and look for the
following in the Capabilities field (see Figure 16-2):
Capabilities: Hardware Flowcontrol In, Hardware
Flowcontrol Out
If there is no mention of hardware flow control in this field, hardware
flow control is not enabled on the line. Hardware flow control for
access server-to-modem connections is recommended.
For an explanation of the output from the show line command, see
the “Using debug Commands” section earlier in this chapter.
