OK.  Seems to be set up pretty much as you write, and the thing works
apparently pretty good.  Services entry is fine, and daemons started using
the hylafax script.
(This *isn't* included in the 4.0pl1 binary dist for SunOS... had to get it
from source dist).

Running the standard Windows NT telnet client, connecting to the Sun server,
explicitly to port 4559 (and getting the banner from hfaxd, so definitely
the right port).

It *is* a Mickeysoft product, granted...;-) That ignores the fact that the
same client can connect and negotiate well with other command-protocol-based
servers like sendmail, and that the same message is displayed by WHFC (which
ain't MS).
