So all I need are link pulses to fake the other end of an Ethernet connection to keep it alive?
This makes building a data diode much simpler than I thought it needed to be. Thanks!
Yes, but this is only the case with 10BASE-T. Modern standards use more complicated Fast Link Pulses.
Also applies to 100Base-T which is still a usable solution for basic networking.
