The script will probably try to enter enable mode, it will also issue a term len 0 command.
If you still have problems post a debug log. (ensure to **** out any sensitive data)
A debug log file records the communication between CatTools and the device you are having trouble with. You can create a debug log file as follows :
# Use the CatTools File menu to select the "Enable capture mode" option.
# Run the activity you are having trouble with. This should create a debug file in the \Debug folder.
# Remember to deselect the "enable capture mode" option again.
Thanks it looks like the account needs show and terminal command in order to run backup.
No worries. Glad to hear you got it working.
