#Notes:
# If not like Tea*Speak then some applications may not recognize the Query
# Default Tea*Speak 3 MOTD:
# TS3\n\rWelcome to the Tea*Speak 3 ServerQuery interface, type \"help\" for a list of commands and \"help <command>\" for information on a specific command.\n\r
# NOTE: Sometimes you have to append one \n\r more!
#The value must be a string
