[Elecraft] K3/K3s Ethernet Interface

[Gerry Hull]

There is plenty of Ethernet-to-RS-232 hardware around if you want to roll
your own.

http://www.ebay.com/itm/RS232-RS485-to-TCP-IP-Ethernet-Serial-Device-Server-NEW-/301230345289?pt=LH_DefaultDomain_0&hash=item4622ba4c49

$19, connect via TCP, TCP Server, or UDP, UDP server.

I find surplux Moxa Serial servers on ebay.  I got a 24-port 1U RS232 box
for $50...  Drivers are available for Windows or Linux.
