My PDP11/53

Another thing to try is to be sure that your terminal is working properly.
Be sure that with the cable attached to the terminal and disconnected from
the 11/53 there is no echo of characters typed at the terminal and when pins
2 and 3 are shorted together on the cable end that would attach to the 11/53
the terminal does echo back to itself. If this does not work, then you have
not properly faked out the modem control signals that the terminal requires
to work.
