I have a fairly urgent need to connect a Hayes compatable modem to a
DTC/72MX DDP RJ45 terminal port.  The modem is a Practical Peripherals
PM288MT II V.34.  Does anyone know the correct RJ45 to DB25 pinouts (and
other pointers) to make this work?

I have tried:
    A terminal adapter/null modem adapter combo.  With and without pins 2 &
3 reversed.
    And, a printer adapter (with and without a null modem adapter) pinned as
follows:

        RJ45     DB25
          1 ----- 2
          3 ----- 3
          4 ----- 20
          6 ----- 7

I don't see any other combinations in the "DTC Cabling and Racking Guide"
that might work.

BTW - the modem has default settings with the exception of S0=1 (for auto
answer).  I can connect to the modem - but, get no response from the DTC.

Many thanks,
Steve
