board will now bootstrap and download the monitor program.

3.6 Verifying that the Monitor is Loaded
Make sure the TTY window is active, clicking the mouse inside the TTY window to activate it if
necessary. Then type the letter ‘
H ’ (case insensitive) to verify that the monitor program is
responding. The ‘H’ command displays the available single-letter commands the monitor will
recognize.
The READS monitors use single-letter commands to execute basic functions. Port configurations
and data, as well as memory inspection and modifications may be accomplished by the monitor.
Most of the single-letter commands are followed by 4 hexadecimal digit addresses or 2
hexadecimal digit data bytes. The following is a list of the commands.
