70 MS-DOS User's Reference
Examples:
If you want your computer to send its printer output to a serial
printer, you need to use the mode command twice. The first
mode command specifies the asynchronous communications
modes, and the second mode command redirects the computer's
parallel printer output to the asynchronous communications port
specified in the first mode command.
For example, if your serial printer operates at 4800 baud with
even parity, and if it is connected to the COM1 port (the first
serial connection on your computer), you would type the
following:
mode com1:48,e,,7p < \
mode lpt1:=com1:
If you redirect parallel printer output from LPT1 to COM1, and
then decide that you want to print a file using LPT1, you can sim
ply type the following command:
mode lpt1 :
This disables any redirection of LPT1. i i
Suppose you want your computer to print on a parallel printer
that is connected to your computer's second parallel printer port
(LPT2). If you want to print with 80 characters per line and 8 ( )
characters per inch, you would type one of the following
commands:
mode Ipt2: 80,8
u
mode Ipt2: ,8
If you want your computer to keep trying to print a file until your (J
printer is ready to print it, type this next command:
mode lpt2:80,8,P , >
To stop retrying to print, you can press control-break or type the
mode command without the P option.
Note If you print files every time you start ms-dos, you may want
to include mode commands in your autoexec, bat file. See ( )
Chapter 4, "Batch Processing," for more information on the
autoexec, bat file.
