[hpsdr] Programming fixed IP address in Hermes

[Gregory Ratcliff]

Seems like three or four of us have set their hermes to 255.255.255.255.   Why is this address chosen?  I'm happy with mine assigned one with dhcp, which is fixed in router setup to always assign 192.168.1.22, based on its MAC.

Comments?
