[HECnet] MMJ to DB9 serial adapter

[H Vlems]

There are several connector models that fit a DE9.
The H8571-J works for me for all my Alpha's as well as VAXstation 4000
and VAX(station) 3100 models.
The H8571-J works in combination with the 25-pin H8571-E (male) and 
H8571-A (female).
The H8575-B only works in pairs, not with any of the H8571-x models,
no idea how it is wired inside.
