A couple of weeks ago, I posted a help message about connecting a US
Robotics MP/8 modem bank up to a DTC48 on an HP 3000.  I received a number
of replies, and really appreciate the help.  As a result of the replies, we
were able to get the modem bank working; however, there were some
variations in the configuration info we received, so it took a while to
zero in on the optimum config.

Anyway, the following info documents our findings.  I hope others in the
future can use this.

CABLE PINOUTS:

US ROB. RJ-45                                        HP-DTC DB25 Male
-----------------------
----------------------------
         1                 Ring Indicate                           20
         2                 DCD                                        4
         3                 DTR                                        6
         4                 SGND                                      7
         5                 RX                                           2
         6                 TX                                           3
         7                 CTS                                       22
         8                 RTS                                         8

             NOTES:  1. The DTC ignore Ring Indicate anyhow.
                           2. US Robotics doesn't have DSR output.


AT COMMND SETUP STRINGS:
-----------------------------------------------
AT&F
ATB0C1E1F1Q0V1X1
AT&A1&B1&C1&D2&G0&H0&I0&K1&L0&M4&N0&P0&R1&S1&T4&X0&Y1
ATS0=1S58=1
AT&W

            NOTES:  1.  ALL 0=zero (there are no letter O's).
                          2.  We had to set S58=1 (DSR) to get the thing to
answer.


DIP SWITCH SETTINGS:
------------------------------------
Switches 3, 8, and 9 are set to ON.


Everything works fine, except the user must press <Enter> after connection
to get a DTC prompt.  (Some of our old modems do not require pressing any
keys to get a DTC prompt.)  This may be a result code suppression disabling
the carriage return in the connection sequence.

Anyway, thanks again to all who responded!
