Serial MS-DOS Commands

 

Most IBM compatible computers default to a parallel printer port. To

 

ensure that information is sent to the serial printer port, type the

 

following MS-DOS commands at the MS-DOS prompt, or include

 

them in the AUTOEXEC.BAT file.

 

MODE COM1: 9600, N, 8, 1, P

 

MODE LPT1: =COM1

 

For MS-DOS version 4.0 or above, enter:

 

MODE COM1: 9600, N, 8, 1, B

 

MODE LPT1: =COM1

 

 

Note

These examples assume that you are using serial printer port COM1.

 

If you are using COM2 or COM3, replace COM1 with the printer port

 

that you are using.

 

Since the MODE command is an external MS-DOS command (a

 

 

program named MODE.COM is run when the MODE command is

 

invoked), the program file must be contained either in the root

 

directory or in a directory specified in a preceding PATH command in

 

the AUTOEXEC.BAT file.

 

After changing the AUTOEXEC.BAT file, reboot the computer to

 

initiate the changes.
