subscribe - Subscribe to a record set. See Meteor.subscribe.
call - Invoke a method. See Meteor.call.
apply - Invoke a method with an argument array. See Meteor.apply.
methods - Define client-only stubs for methods defined on the remote server. See Meteor.methods.
status - Get the current connection status. See Meteor.status.
reconnect - See Meteor.reconnect.

onReconnect - Set this to a function to be called as the first step of reconnecting. This function can call methods which will be executed before any other outstanding methods. For example, this can be used to re-establish the appropriate authentication context on the new connection.
So basically, you can do
Meteor.connectToRemote = DDP.connect(remoteUrl);
Tracker.autorun(function(){
if (Meteor.connectToRemote.status === 'connected')
// do stuff
}
});
