Those aren't the ones I'm talking about; those are intended as device
servers, not client boxes, where a serial-based system can serve data over
Ethernet. The UDS series (UDS-10, UDS-10-01 and UDS-100) let a system do
*client* access over Ethernet. These are the ones I've used, and I've found
them used for as low as $15-$20.  Their MSRP is around $100 (!) but you can
definitely do better than that. They are still manufactured and supported.
