Appendix B: 68K Monitor Commands
Introduction
This appendix outlines some of the 68K Monitor commands that can be used when
working with D20ME. Instructions in this chapter are excerpts from the 68K Monitor
User's Guide.
Refer to the 68K Monitor User's Guide (P136-0UG) for information about other
commands not listed here.
Changing the
Baud Rate
The D20ME/ME II Monitor has the ability to change the communication speed of
the WESMAINT port. This is useful when downloading large files.
Example: A 1 MB code file may take upwards of 40 minutes to download at 9600
bps (the default). At 38400 bps, the transfer is only 10 – 15 minutes.
Note:
SET BAUD
RATE
command
Most PCs cannot exceed 115,200 bps, and some terminal programs
(Windows Terminal for example) may have other restrictions. Check the
program's User's Guide for help.
The SET BAUD RATE command changes the data rate of the WESMAINT port to a
user-supplied value.

this command be only used to speed up a serial download, and not to redefine the
operational state.
