------------------------  MODE - External DOS Command  -------------------------

MODE has four Options.  Each Option has its own format and parameters:

   1. Sets operation mode on a printer.
   2. Sets operation mode on a color/graphics display.  Also switches between
      display adapters.
   3. Sets options for an asynchronous communications adapter.
   4. Route parallel printer output to an asynchronous communications adapter.

NOTE:  In DOS Version 3, you may preface this command with the drive letter and
   directory path, [d:][path], where the command file can be found.


  --------------------- Set Operation Mode on a Printer ---------------------

FORMAT:   MODE LPT#:[n][,[m][,P]]

REMARKS:

   # - printer number (1,2, or 3).
   n - characters per line (80 or 132).
   m - vertical spacing, lines per inch (6 or 8).
   P - continuous retry on time-out errors.

EXAMPLE: Set the operation mode for printer 1, to 132 characters per line and 8
   lines per inch:

          MODE LPT1:132,8


  -------------  Set Operation Mode on a Color/Graphics Display  -------------
                    (also switches between display adapters)

FORMAT:   MODE n    or    MODE [n],m[,T]

REMARKS:

   n - color and/or width of screen.  The following are valid values for n:

          40   - sets color/graphics display width to 40 characters.
          80   - sets color/graphics display width to 80 characters.
          BW40 - activates the color/graphics display adapter and sets the
                 display to Black and White with 40 characters per line.
          BW80 - activates the color/graphics display adapter and sets the
                 display to Black and White with 80 characters per line.
          CO40 - activates the color/graphics display adapter, enables color,
                 and sets the display width to 40 characters.
          CO80 - activates the color/graphics display adapter, enables color,
                 and sets the display width to 80 characters.
          MONO - activates the monochrome display adapter.  The width is always
                 80 characters.

   m - R or L; shifts display right or left.  40 column displays are shifted one
       character, color/graphics displays are shifted two characters.

   T - requests a test pattern to align the display.  A (Y/N) prompt will ask
       you if the screen is properly aligned.  If you enter N, the shift is
       repeated and you are prompted again.  Enter Y and the command ends.

EXAMPLE:  Switch to the color/graphics display, enable color and set the width
   to 80 characters:

          MODE CO80


  --------- Set Options for an Asynchronous Communications Adapter ---------

FORMAT:   MODE COMn:baud[,parity[,databits[,stopbits[,P]]]]

REMARKS:

   n        -  asynchronous communications adapter number; 1 or 2.
   baud     -  110, 150, 300, 600, 1200, 2400, 4800 or 9600.  Only the first
               two digits are required.
   parity   -  N (none), O (odd) or E (even).  If omitted, E is assumed.
   databits -  7 or 8.  If omitted, 7 is assumed.
   stopbits -  1 or 2.  If omitted and baud is 110, 2 is assumed.  If omitted
               and baud is not 110, 1 is assumed.
   P        -  indicates that the asynchronous communications adapter is being
               used for a serial interface to a printer.  Time-out errors will
               be continuously retried.  The retries can be broken with
               Control-Break.  To turn off continuous retry on time-out errors,
               reissue the MODE command without the P parameter.

EXAMPLE:  Set the communications protocol for COM1 to 2400 baud, even parity, 8
   databits, 1 stopbit:

          MODE COM1:24,E,8,1


  --- Route Parallel Printer Output to Asynchronous Communications Adapter ---

FORMAT:   MODE LPT#:=COMn

REMARKS:

   # - printer number; 1, 2 or 3.
   n - asynchronous communications adapter; 1 or 2.

   Output for printer LPT# is redirected to the specified asynchronous
   communications adapter.

   You must first initialize the asynchronous communications adapter using
   Option 3 "Set Options for an Asynchronous Communications Adapter."  You
   should also specify the P parameter in that initialization.

   To disable the redirection for the specified printer, use Option 1,
   MODE LPT#:[n][,[m][,P]].

EXAMPLE:  Redirect the output of parallel printer 1 to asynchronous
   communications adapter 2:

          MODE LPT1:=COM2
