General syntax format
Commands are constructed with individual pieces of information represented as code. Each command is
structured as follows:
 One-character Delimiter that indicates the type of command to execute.
 Two-character HEX module address, from 00 to FF
 Function, which indicates the task to execute.
 Terminator character, to indicate the end of the command.
This section lists the commands to use to perform specific functions. When writing a command, replace the
generic address with the address of the module you want to perform the task on. For example, to read the
name of module 1:
Select $AAM, the command used to read the name of a module (see page 35).
1. Replace the address (AA) with 01, to indicate module 1.
2. Terminate the command with a carriage return (cr).
This command would then be written as $01M(cr).
