Have you tried SSH2 no pty as the connection method?
If you still have problems can you create a device capture and post it here. A device capture file records the communication between CatTools and the device you are having trouble with. You can create a device capture 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.
# Zip up the resulting file and send this to me as an attachment.
# Remember to deselect the "enable capture mode" option again.
Please ensure that you *** out any sensative information.
It didn't capture much. I don't have any problem posting what it captured:
And, this is with the "nopty" option.....
