This is information for users of the MS-400 four port serial card but
also applies any board where the serial ports share interrupts.

First install BB normally.  If you encounter excessive overrun errors
(more than 1 evey 15 minutes or so), modify your PARMS.BB to use
the INTERLOCK_COM parameter.

Example: Suppose COM3, 4, and 5 are shared.  Your PARMS.BB would look
like:

    PORT
      ...
      COM = 3
      ...
    ENDPORT

    PORT
      ...
      COM = 4
      INTERLOCK_COM = 3
      ...
    ENDPORT

    PORT
      ...
      COM = 5
      INTERLOCK_COM = 3
      ...
    ENDPORT

Each use of INTERLOCK_COM slows down the operation of the BBS so use
sparingly.  If you have 3 ports shared, try just interlocking two and
leaving the other free.  If you have 4 ports, interlock 2 and 2.

Four Port Example:  COM3,4,5,6 are an MS-400 card


    PORT
      ...
      COM = 3
      ...
    ENDPORT

    PORT
      ...
      COM = 4
      INTERLOCK_COM = 3
      ...
    ENDPORT

    PORT
      ...
      COM = 5
      ...
    ENDPORT

    PORT
      ...
      COM = 6
      INTERLOCK_COM = 5
      ...
    ENDPORT
