Command Str u cture
Each ML command begins with a start of command character (the
"@" symbol) followed by a command, an address, an optional data
field and terminated by a carriage return. If there is data, it
will be presented as parameter fields separated by commas. All
characters except the terminating carriage return must be
printable ASCII characters.
One exception are optional <STX>
and <ETX> characters (not shown), which are ignored, but allowed
for the sake of compatibility.
Command Structure
@ {cmd}, {addr}, [{param1},]    [{param1},] [CHK] <CR>
Where:
, = Comma (field separator)
@
= Start of Command (40 hex)
{Cmd} = Command Character
{Addr} = Address
{ParamX} = Parameters (optional)
[CHK]
= Optional Data Verification Field
<CR> = Carriage Return Character (0D hex)
Starting and Ending Commands
An ML command is started by sending an "@" (40 hex) character
and terminated by a carriage return (0D hex). The Monitor Labs
protocol calls for an optional <STX> character (02 hex) as a
start of command and <ETX> character (03 hex) as an end of
command character. These characters may be included, but will
be ignored by the
2010D
.
Command Words
Command words are one or more characters in length. Any
combination of printable letters, numbers or symbols (except the
start-of-command character, "@") may be used in commands.
Command words are not case sensitive.
