I have a vt100 terminal which I cannot get out of half duplex. I haven't been able find to find any reference to this in the manual that I have for it. Is the vt100 capable of operating in full duplex mode? The terminal does not have the extended video board.

It doesn't sound like an ordinary VT100 to me. Perhaps it's really a VT132, in which case one of the SET-UP bits (I think the third bit in the fourth block, but I'm not sure) controls LOCAL ECHO mode; try toggling it. It is also possible that you have a VT100 equipped with DEI's RetroGraphics board, which has its own set-up menu that includes local echo (half duplex); as I recall if you press PF1 within a second or so of a terminal reset, you'll enter the RetroGraphics menu.
