I have (2) 3310 NAC appliances that someone else set up and configured. I need to access via a serial connection to my laptop to upgrade the software. I cannot connect via Hyperterm. I have 4 other NAC appliances that I can connect to fine via direct laptop serial connection. My hyperterm settings are correct. Log files do not show anything that could be causing this (per TAC). I can access via ssh over the network, and through the web gui.
I have this problem too.
