You could also make one with a pair of reasonable quality DPDT relays and a
transistor driven off a serial or pa

Kevin,
I just installed a TE210P. Since I see you work at Digium, presumably
you know what you are talking about.
If what you saw is correct.. then what are the different blink 'codes'?
For instance.. if I bring ZAP up without a PRI cable connected it kind
of dims up and then dims down.

How about using a relay? There are ways to control relays using serial,
parallel and usb ports. I'm sure someone makes a suitable relay for the
need.

Indeed, they don't. But have a look at the fail-over switch that
Junghanns.net is making.
I haven't tried it but by the looks of it it is just a relatively simple
piece of hardware switching your pri over to another box in case of
failure.
