When I setup the following:

if (bServer)
{
    UdpSocket->RemoteHost = "<Any>";
    UdpSocket->RemotePort = 0;
    UdpSocket->LocalHost = "<Any>";
    UdpSocket->LocalPort = 34100;
}
else
{
   UdpSocket->RemoteHost = "192.168.0.27";
   UdpSocket->RemotePort = 34100;
   UdpSocket->LocalHost = "<Any>";
   UdpSocket->LocalPort = 0;
}
UdpSocket->Open();

there are no errors when bServer is false, and the Event UdpSocketConnect is called.
When bServer is true the event UdpSocketError is called with socket error 10049. If I then change RemoteHost to 127.0.0.1, then UdpSocketError is not called, but if it shall work as a server, the remote host cannot be specified. So how shall it be setup to a server ?
The C Builder Developer's guide say, on page 37-7, that the LocalPort property shall be set, and nothing else. It also says that there is an OnAccept event, that is called when a client has connected, but UdpSocket don't have this event. 
For client sockets it says that the remote port and remote address shall be set and nothing else.
