Symptoms: If a Cisco 2800 series router is configured to do async tunneling using sync/async
module with very slow speed like 2400bps or below, the sync/async line may get in stuck state.
Entering the show tcp command on that stuck line shows CLOSED TCP connection with some
unread input bytes, for example:
module with very slow speed like 2400bps or below, the sync/async line may get in stuck state.
Entering the show tcp command on that stuck line shows CLOSED TCP connection with some
unread input bytes, for example:
Router#sh tcp
tty0/2/0, connection 1 to host 172.16.242.129
Connection state is CLOSED, I/O status: 7, unread input bytes: 97
Connection is ECN Disabled
Local host: 172.16.146.249, Local port: 20514
Foreign host: 172.16.242.129, Foreign port: 23

Conditions: This symptom occurs only when the Cisco 2800 series router is used for async data
tunneling at line speed of 2400 bps or lower with wic-2a/s card
tunneling at line speed of 2400 bps or lower with wic-2a/s card
Workarounds: See the following:
1.
Issue the clear line x/y/z command to make that line usable again
2.
Use Cisco IOS Release 12.3(14)T7, which does not show this issue as readily as Cisco IOS
Release 12.4.
Release 12.4.
3.
Use line speed higher than 2400 bps.
4.
Use aux port of 2800 router.
