	Could be the terminal itself and/or the cable hookup. Might
want to recheck everything on that side and make sure it's working
right and the pin's are assigned correctly, flow control, etc. That
is odd though, perhaps reseting the NVRAM just to be safe wouldn't be a
bad idea.

	I've never opened one of the switching regs in my 2xx series
DECstations, but I imagine that there is probably a wire or a jumper block
that you have to move *inside* the switching reg. to alter voltages. Only
newer P.S.'s have autoswitching or switched on the exterior. I could be
wrong though.
