USR - MSNP8-MSNP14

Dispatch Server/Notification server

This command is used to authenticate a client with the notification server. If the client is connected to a dispatch server, the initial USR command sent by the client will be replied with a XFR command by the server, followed by disconnection. The XFR will contain the address of a suitable notification server that the client should connect to, to continue authentication.
