Well, the comm settings are dipswitches on the DL11-W serial port/line
clock board.

The cable's a null modem. (The PDP11 doesn't use any flow control on it
so it should be something like this: (BTW -- you may just need to
get 6 and 8 to 20 on the PC side if the PDP11 DL doesn't assert DTR.

               PDP PC
                2<->3
                3<->2
                7<->7
               
                   -4
                  |
                   _5

                   -6
              20--|
                   -8

                   
Anyone have the DL11-W dip switches.

The console usually runs at 1200 Baud (if it had an LA120), 300 baud
if it was an LA36, or 9600 baud for a Video Terminal like a VT100 or
VT52.
