[Elecraft] Remoting the K2

[Larry Phipps]

A router with DDNS support can do this automatically. Plus, the firewall 
is only open to a piece of hardware that converts serial port data into 
TCP port data... not to a PC. Nobody is going to hack into a black box 
with dedicated firmware when there are millions of Windows machines out 
there to hack into. There is very little risk in that, unless I'm 
missing something (not unheard of, BTW ;-)
