ISDN-TA and HDLC-PPP troubles (fwd)

To followup on my onw posting:
I asked:
=> We're supporting ISDN access for x.75, v110 and v120 currently.
=> But some MAC people claim they can only do PPP over HDLC, so as a test
=> I've hooked up a ELSA terminal adapter to a portmaster and set it
=> to async PPP to HDLC.
=>
=> Then I went home and did the same for my adapters at home. I used both
=> an ELSA TL/v.34 and an ZyXel I2834. And in both cases the portmaster
=> did not recognise the PPP coming from the adapter as real PPP.
=> (Or atleast set debug 0x51 does not give any PPP on the port.)
=> Where as I attach to the port, It seriously looks like PPP, if only
=> because there's plenty of {}"s.

I've gotten as far as:
The portmaster sees the PPP-requests coming in:
LCP_CONFIGURE_REQUEST
it acknowledges with:
LCP_CONFIGURE_ACK

But this never makes it to the terminal adapters.

Now this could be due to the fact that the adapter on the portmaster still
sees the login messages after activation of the CD.

So the question now becomes:
HOW do I disable the login-text stuff on a port, and get it to
default to:
Modem connect, hangup after CD goes down
PPP
PAP authentication, otherwise hangup within 1 minute

Thanx,
