AUTOEXEC.BAT Standard Configurations

Parallel DOS Commands

If the previous check did not produce the desired result, ensure that the AUTOEXEC.BAT file contains the following statements for parallel interface communications:

MODE LPT1:,,P

For MS-DOS version 4.0 and above, enter:

MODE LPT1:,,B

N o t e

This example assumes that you are using parallel

 

printer port LPT1. If you are using LPT2 or

 

LPT3, replace LPT1 in the example with the

 

appropriate printer port.

If the problem persists, proceed to Table 7-30 “Communications Checks.”

Serial MS-DOS Commands

Most IBM compatible computers default to a parallel printer port. To ensure that information is sent to your serial printer port, type the following MS-DOS commands at your MS-DOS prompt, or include them in your 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

N o t e

These examples assume that you are using serial

 

printer port COM1. If you are using COM2 or

 

COM3, replace COM1 with the appropriate

 

printer port.

If the problem persists, proceed with the following checks in Table 7-30.
