HP GbE2c running iscli hangs with Enable password set


Has anyone configured HPGbE2c switches for blade enclosures on Cattools? We have a lot of blade switches here and I have upgraded FW on switches to virtually the latest version (5.1.2). I was able to get configs off a couple of switches by switching to ISCLI mode (virtually IOS). As soon as I put an enable password on, the back up fails as the switch seems to need an extra Carriage Return between telnet login and enable login. I used Cisco switch IOS  and Cisco Other for my device and model type respectively; although I have since tried others and they too have failed. Any help, suggestions, greatly appreciated.
