Has anyone made their own serial over ethernet converter?

As in serial -> Ethernet -> serial
Using commonly available hardware what sort of latency and max baud rate are practical?

Rerouter:
Latency will be determined by the packet routing and normal network stuff, maximum baud rate comes down to the end points, and how congested your links are, e.g. what happens when a packet goes missing, what happens when they arrive out of order, and if it responds differently to what you expect midway through you sending the next command, how do you handle this?

I was thinking of a dedicated point to point ethernet link.

Rerouter:
same wire, or through a switch / router?

No need to reinvent the wheel:

Questions for latency and bandwidth: depends on application. Usually UART and interrupts limit realtime capabilities of e.g. RS232 serial connections as well.

Should you intend to packetize the whole serial protocol with handshakes and such... i kind of doubt it works the way you think, because of flow control, frame sizes and checksums.
