This depends on what kind of "terminal" you're using. You need something both sides understand. Examples I've seen on other forms of unix include kermit and zmodem.
I don't have access to either of your systems. You are going to have to look at your systems to see what is available to you.
If I was using hyperterminal on XP to connect to HP-UX.... I click on transfer in hyperterminal , then Receive File. The pop-up window give me a list of protocols. I see that one of them is xmodem. I see that HP-UX has "umodem -- XMODEM-protocol file transfer program", so I would try that.
Now you must look at both sides of your connection and find what is available to you.
I believe if you have zmodem available, that protocol is faster than xmodem. Like Perderabo said, you need to figure out what's available, but if you have zmodem, use it.
