I picked this up the other day. I THINK it's a hand held terminal. It was made by Two Technologies Inc of Horsham, Pa and it's model number is TT1-R2-2. It's a blue box slightly larger than a pack of cigarettes and has a LCD screen and a membrane type keyboard. The keyboard seems to have all the usually alphabetic, numeric and puctuation keys plys F1 to F5, Shift, Control, Space, Back Space and Enter. it has a curly cord on the bottom. The curly cord has RJ-11 six pin connector on each end. It does not have any batteries or power connection so it must get it's power from what ever it's plugged into. I searched the net but didn't find anything about Two Industries or this device. Is anyone familar with it? Joe
