     Has Anyone have been able to get a Telebit Plus to work on a 
HP 9000/825 with Mux 98196A ?

      The cable that I have used from the Multiplexer to the modem has the
following pin outs.

        1 ----------- 1
        2 ----------- 3
        3 ----------- 2
        4 ----------- 5
        5 ----------- 4
       20 ----------- 6
        6 ----------- 20

       also tried the cable as suggested in the HP Multiplexer manual.
i.e.

        1 ------------ 1
        2 ------------ 3
        3 ------------ 2
        4 ------------ 8
        6 ------------ 20
        7 ------------ 7
        8 ------------ 4
        9 ------------ 22
       20 ------------ 6
       22 ------------ 5 
       23 ------------ 23

  But none of them worked.


      The entries for the Systems ,Devices ,Dialers and /etc/inittab files are


     civ Any ACU 9600 3915
   
-  Entry in the Devices file

     ACU ttyd0p5 - 9600 tbfast

-  Entry in the Dialers file

     tbfast  =W-,  ""A\pATE1M1Q0V1X0S7=45\r OK ATDT\T CONNECT\sFAST

-  Entry in the inittab file

     c5:0123456:respawn:/usr/lib/uucp/uugetty -r -t60 ttyd0p5
 
     The registers of the telebit modem is

E0 F1 M1 Q3 P V0 X1
S00=1 S01=0 S02=43 S03=13 S04=10 S05=8 S06=2 S07=40 S08=2 S09=6
S10=7 S11=70 S12=50
S45=0 S47=4 S48=0 S49=0
S50=0 S51=4 S52=0 S53=0 S54=0 S55=0 S56=17 S57=19 S58=3 S59=0
S60=0 S61=45 S62=3 S63=1 S64=0 S65=0 S66=0 S67=0 S68=255
S90=0 S91=0 S92=0 S95=0
S100=0 S101=0 S102=0 S104=0
S110=255 S111=30 S112=1
S121=0

    I tried the following command but none of them worked

   cu -d9 civ

   cu -d9 -s9600 -l/dev/ttyd0p5

    The symptoms of the problem is when dialing with the modem speaker on
I couldn't hear the dial tones at all.  - Looks likes the modem "is not
"connected to the Multiplexer at all.

    Is the multiplexer a DTE or DCE ?  From the wiring, I would assume it
is a DCE, am I right ??

     Any help would be much appreciated.
