Ignore the 'model' field. This is purely a reference field and you can add whatever you like in there. It doesn't effect the way the script works.
The 'hit any key to continue' shold be automatically handled by the script. Just try setting up the device up in CatTools with no username and passwords defined.
Leave the stack option empty too unless you have a stack of HP switches and see the "Enter switch number to connect to or <CR>" prompt when you connect, in which case you need to enter the stack item number in this field
