Client Mode Changes
The notion of a mode setting is to allow the server to select between optional behaviors or parameters in the
client. If the server wants the client to adopt a certain mode setting, it sends the command. The client will
do so, if applicable. If not, optionally, an error report may be generated in response. Mode values are set
by using token–value pairs. Mode values can be queried by sending the mode name alone. Error reports
are used primarily as a debugging tool. The string starts with an error number, optionally followed by
white space and explanatory text.
