class	Cx
	Base class for network/file data transfert. This class contain only methods related to data transfert (send, receive). Use a derived class to be able to open a connection, like FileCx or TcpCx. You can send/receive arbitrary data or file, or you can use the Packet class that already contains useful attributes. More...

class	TcpCx
	Implements TCP networking. This class implements TCP/IP data connections. Nagle algorithm is turned off, to speed up little but frequent transfers. More...
