Pretty dramatic difference between a "real" serial port and USB. Like two

If you computer lacks a serial port, just buy a new computer. The
Raspberry Pi or the like costs about $40.... the serial port has a pin that is
tied to an interrupt. If
you read the code associated with that interrupt it is like maybe 4 or 6
lines of C and VERY simple.

Great for picking up the PPS.
Know of any with an Ethernet port, preferably two, that aren't run from
a USB controller?
