This Pat connection attempt:

L[ax25]> connect seoc

2022/05/04 17:18:05 Connected to W8CMN-2 (AX.25)
*** Failed to Connect
2022/05/04 17:18:10 Exchange failed: connection lost

whose packets look like this:

leaves this dangling socket:

Active AX.25 sockets

W8CMN-2    KB8ZQZ-0   ax0     LISTENING    001/000  0       0

Exiting pat interactive and restarting clears the dangling socket.
