* Message categories supported by the messageEnabled() function and other assorted message
|
|
* functions. Each category has a corresponding bit value that can be combined (ie, OR'ed) as
|
|
* needed. The Debugger's message command ("m") is used to turn message categories on and off,
|
|

|

|
|
* m port on
|
|
* m port off

|
|
* NOTE: The order of these categories can be rearranged, alphabetized, etc, as desired; just be
|
|
* aware that changing the bit values could break saved Debugger states (not a huge concern, just
|
|
* something to be aware of).
