and active video display.
Syntax
MODE LPT#[:]=COM#[:]
MODE COM#:baud[,parity[,databits[,stopbits[,P]]]]
MODE video mode
MODE display lines
Remarks
The first syntax above redirects line printer output to the serial port.
The second syntax above changes the operation of the specified
communications port. The options that can be modified are listed below.
Invalid values for any of the options are flagged with an error message.
baud
110, 150, 300, 600, 1200, 2400, 4800, 9600
parity
N - None, O - Odd, E - Even
databits

stopbits

P
Printer Port
Using the
P
option as the last argument causes output to be sent
repeatedly to the printer port until successfully received. Without the P,
output is sent only once, causing a critical error if unsuccessful.
The third syntax changes the active
video mode
for the display terminal.
The valid choices for this version of the MODE command are as follows:
40
— Indicates 40 characters per line.
80
— Indicates 80 characters per line.
