We use another device to accomplish the same objectives. Its a small unit
made by Rabbit Semiconductor. We used their development kit to build a
single connection telnet server and also added a relay for remote power
cycles. The SNS guys put together a packaging design that incorporates a
powere supply, rabbit board, relay, and receptacle on a din rail. The
rabbit board sells for about $150. I don't recall the prices of the other
components. We would gladly provide our software.

Using this device we can observe VxWorks boot messages and perform a
remote power cycle of the IOC.

This is a very nice product. The development kit comes with a number of
example applications. In half a day I was talking to the board from a
telnet client and a web browser (the telnet server and http server are
different applications; I could do one or the other).
