MODE COMMAND

Purpose:  Sets the mode of a printing device, color graphic display or
          asynchronous transmission adapter.

Syntax:   [d:] [path] MODE <arguments> -----+
                                            |

1. Redirection of standard printer output
          PRN[:] = <DeviceName>[:]

2. Setting of the printer mode
          LPTn[:] [[COLS=]c] [[LINES=]l] [TINY] [[RETRY=]r]
                  [[CHARS=]c] [ QUALITY= DRAFT|NLQ ]

3. Setting of the serial port mode
          COMn[:] [BAUD=b] [DATA=d] [STOP=s] [PARITY=<ODD|EVEN|NONE>]

4. Setting of the display mode
          [CON[:]] MONO|CO80|BW80|CO40|BW40| BiosModeNumber
                   COLS  = m (40,80)
                   LINES = n (25,30,43/50)
                   [/B][/V][/N]

Setting of the keyboard mode
          [CON[:]] RATE=r DELAY=d

Type:     External command

Description:

Variant 1. Redirects Input/Output from PRN device to the device, specified
           by the user.

Variant 2. Sets the mode of IBM-EPSON compatible printers, connected to
           the parallel ports (LPT1 - LPT3).

Parameters:

n        Specifies the parallel port number: 1,2,3
c        Specifies the character per line: 40,80 or 132
l        Specifies the character per inch: 6 or 8
r        Specifies the retry action to take when time-out error occurs.
         'E' - returns the error, when the device is busy
         'B' - returns 'busy', when the device is busy
         'R' - returns 'ready', when the device is busy
TINY     Sets the minimal size characters printing mode
QUALITY  Sets the ordinary print mode - DRAFT or quality print mode - NLQ

Variant 3. Controls the configuration of the serial port adapter.

Parameters:

n        Specifies the number of the serial port;1,2,3,4.
b        Specifies the transmission rate:
         110,150,300,600,1200,2400,4800,9600 bits per second
p        Specifies the parity: NONE, ODD, EVEN.
D        Specifies the number of data bit: 5, 6, 7 or 8
s        Specifies the number of stop bits: 1, 1.5 or 2

The default value is 7 data bit and EVEN.

Variant 4. Specifies the active video adapter and its display mode or
           resets the current mode of adapter display.

Parameters:

BiosModeNumber  Specifies the number of the display mode:
                BW40, BW80, CO40, CO80 or MONO.
m               Specifies the number of characters per line: 40 or 80
n               Specifies the number of lines on the display:
                25,30 or 43/50
/B              Using default BIOS interrupt
/V              Using default VGA interrupt
/N              Allows you not to check the display type

BW40            switches a color graphics adapter and specifies a monochrome
                display adapter with a display of 40 characters per line.
BW80            switches a color graphics adapter and specifies a monochrome
                display adapter with a display of 80 characters per line.
CO40            switches a color graphics adapter and specifies color display
                adapter with a display of 40 characters per line.
CO80            switches a color graphics adapter and specifies color display
                adapter with a display of 80 characters per line.
MONO            initialize a monochrome display adapter with a constant
                display of 80 characters per line.

Variant 5. Sets keyboard typematic rate.

Parameters:

r   Specifies the typematic interval time. The range for possible values
    is 1-32.
d   Specifies the auto-repeat start delay time. Possible values are 1-4.
    (Respectively .25, .50, .75 and 1 second).
