We are searching for a new serial to ethernet solution which is not as expensive as most B2B products. Right now this [1] would be our dream product. We are also looking into a combination of a mini-pc (like PC-Engines [2]) with two of these miniPCIe serial cards [3].

If you have better recommendations feel free to share them :)

I've used Startech FTDI based multi-port serial to USB adapters along with a Mikrotik Routerboard to make serial-to-ethernet or serial-to-LTE boxes. The Mikrotik boxes expose the serial port on a TCP port for you to connect to.

Old multi-port serial consoles can often be found used quite cheap.

Personally, I'm a big fan of the OpenGear units. They're *much^ more than just basic serial consoles and are quite extendable. You can even write your own scripts to interact with them, trigger them on specific events, and so on.

Yeah +1 for OpenGear console servers, I've used them for years. Looks like there are some bargains to be had on ebay, I see a 32 port one for $150...
