And it should compensate for using a cross cable instead of a straight
one, it should provide both DB9 and DB25 connectors (both male and
female, + the RJ connectors that were used by Digital), it should
tolerate non-inverted signals, TTL level signals (both 5V and 3V), and
of course all other current and future user errors and design follies.
But it might require a certain phase of the moon to do so, and waving of
a certain dead sea creature.
