Bill Kennedy saves the day!  It turns out that there are subtle differences
in AT&T 3.1 UUCP, AT&T 3.2 UUCP, and Enix 3.2 UUCP, and that was what
tripped me.

Modem control was indeed the problem.  A friend running 3.1 sent me his
UUCP setup that worked without it; the setup sortof worked on Enix and
sortof worked a different way on AT&T 3.2.  Bleah!   I tried RTFMing
early on, but it seemed obscure on this point at best.

Mr. Kennedy also points out that Enix (and apparently Interactive as well)
needs DCD forced high (S53=0 on the Telebit), and that the tty permissions
have to be set correctly (666, or owned by UUCP).

Good luck to everyone else hacking his/her way through the RS232 jungle ... :)
