Sorry for bumping, but maybe it can help to someone:
There is an easier way by execing the "connect 80.69.77.181:28960" command in connect.menu, or in the menu, which is opened immediately after a player has connected:
Theoretically it should be executed sooner, and it will also free up the "clientcmd" menu, which can be useful if your mod almost exceeded the menu limit :PCode:onOpen { execNow "connect 80.69.77.181:28960" }
