Moxa has some really neat serial-to-ethernet boxes.

I have seen such devices. The problem is the non-deterministic nature
of packets on the ethernet, versus the hardware interrupt caused by
the serial port line toggle done by the GPS.

Sure, I didn't mean to suggest this would be any good for a PPS signal.

But we are always looking. Serial ports are going the way of the dodo.
Even if there are some real world needs for them. Just not enough of
them to keep them standard on consumer grade computers.

At least you can get plug-in cards - I bought an 8 port card a couple of
years back when you could still get cards with PCI interface :-)
