Background:	VAX 750, VMS 4.1, DMF-32, DF112-A
Problem:	set host/dte/dial

I am having problems using `set host/dte'.   There is a DF112-A connected
via pins 2,3,5,6,7,8,20,22 (all straight through) to port 1 of a DMF-32
(txa1) which is started as
	$set prot=(s:r,o,g,w)/own=[1,4]/dev txa1:
and
	$set term txa1:/perm/nowrap/fulldup/autobaud/par=even/eight-
		/hostsync/readsync/ttsync/form/hangup/altype/dialup/modem
It seems to work fine as a dial-in port.

When I try (where xxxxxxx is an actual number)
	$ set host/dte txa1: /dial=number:xxxxxxx

I get the message (very quickly):

Failed to connect to remote port
%SYSTEM-F-HANGUP, data set hang-up

Upon a retry, the port shows as allocated to another user.  Sure enough,
there is a process running loginout on that port.  Shortly thereafter, there
occur several sets of three `dialup interactive breakin attempt' alarms on
that port, all with garbage-style usernames and passwords (like @XX/X~),
indicating phone line noise (of which I see none on a normal dialin).

If I turn off /HOSTSYNC and /READSYNC at least I don't get the garbage login
attempts, but still the same data set hang-up message.

Help!!  What's going on here?
