7.3.1. Get Command
The 'GET' command can be used to get the child nodes, properties and methods of a specific node. It can
also be used to get the value of a property.
The Response Format
The first two characters of a response unambiguously identify the type of the element that the response
line concerns. The first character is the type of the element (node, property or method), the second is for
miscellaneous information (e.g. read/write rights).
The defined prefixes are:
'n-':
'pr':
'pw':
'm-':
After the prefix, the response contains the full path of the node, property or method after a space character.
