Ah, OK, so my cable is physically crossed - if I hold the plugs side-by-side
the colours run in reverse order. And Googling 'BC16E-10' suggests this is a
crossover. So assuming the MMJ port on my VT420 marked '1' (plus arrows) is
not broken it is likely I have a cable for a printer.
All of my cables on hand are physically reversered - {white, green,
red, orange,black, blue} on one plug and {blue, black, orange, red,
green, white} on the other plug on the other end of the cable.
That is type of cable I used to plug directly from a KDJ11-SD /
M7554-SD to a VT320 with no adapters at either end of the BC16E cable.
Not sure why that wouldn't work for you.
Are you also using a KDJ11-SD / M7554-SD (or -PB)? I'm not sure if
any other 11/53 versions had MMJ console ports. Mine originally came
from a DECserver 550 CPU and I reprogrammed the EPROMs
with 11/53
firmware.
