5BRI + Dialback-Login-User

We've just received a 5BRI module to test interoperability with our other ISDN
gear. It seems to work, *EXCEPT* for a Dialback-Login-User. It seems that the
PM is trying to use an Async dial script to connect, which doesn't work.

Here's the output of me dialing in, and the debug output from the PM:

Dialing...
CONNECT 64000
ETH/IIS Portmaster -- Authorized Use Only

login: office
Password:
Dialback Accepted

Call Terminated - Unspecified Cause (31)

S20: Sending Request Connect - 64Kbps / Data
S20: Received Connect - B1
S20: Link Protocol: V120 Rate Adaption
S20: Sending Disconnect Request
S20: Received Disconnect Ack
S20: Received Call Clear
sendthem (AT\r)
expect (\r)
Connection Failed

Is there something special that I need to set in order for this to
work as expected ? I tried setting NAS-Port-Type to ISDN (and ISDN-V120),
without any effect.

The problem is clear. On the 5BRI, when you send it AT, it responds with OK\r,
and not just \r; is there any way to override this ? I didn't find anything
in the manual -- our supplier sent us the board without *ANY* documentation; is
there seperate documentation for the 5BRI board, in addition to the PM2E
documentation ?

We are running ComOS 3.3.2.
