On my SVR2 Altos, there *IS* a "getpgrp".  It would seem to me
that one could grab that and scan the "utmp" file to find what
port the process is on.  If the process has detached via "setpgrp",
it would seem that your "utmp" entry doesn't apply anymore anyway.
(I'd look at my 3b1, but it's at home..)
