state-initializing: properly pre-set port number

The port number used to be 1, but we are multi-port, and forgot to
update this item (no bad effects were seen so far, but the standard
requires each port to use a different port number so loops can be
managed, and, for example, having both Ethernet and UDP on the same
wire is a loop.
