In other words, a terminal server (or a console server, as they're
sometimes called).  Look for a secondhand Shivaport or Lantronix; don't
bother with Emulex.

If you want a really small one, try

(but they ain't cheap).  They do some nice things; I bought some web-IO
thermometer units from them (I use PT100 probes and I can run the
probes remotely over 100m of Cat5).
