I'm not sure what bits were just twiddled... but after logging into the F5 10.1 device interactively and validating the commands, my batch commands are returning as expected. Meaning from a batch SSH connection I am suddenly not seeing the terminal error, and the full output is being returned. No script changes were made. The only step between broken and functioning returns was an interactive login. Could this term information be coming from the interactive shell. No idea.
Anyway, if/when it fails again, I'll have an environment again to reproduce whatever you folks suggest.
