bool ServiceList::SendDimCommand	(	std::ostream &	lout,
		const std::string &	server,
		const std::string &	str
	)		const

Tries to send a dim command according to the arguments. The command given is evaluated according to the available format string.

Parameters

lout	the ostream to which errors and debug output is redirected
server	The name of the server to which the command should be send, e.g. DRIVE
str	Command and data, eg "TRACK 12.5 13.8"

Returns

If parsing the string was successfull and the command exists in the network true is returned, false otherwise.
