Are you perhaps looking for a serial over ethernet device such as the
ones made by Moxa (www.moxa.com)? I'm sure there are other makers of
such devices, but this is what I've used. We buy up old versions of
DE-303, Nport 5610, etc. on ebay for about $100 each. Moxa provides
linux drivers that work great in CentOS. So, CentOS sees a /dev/ttyr00
port and you plug your serial device into the Moxa and you're good to
go. A great solution for virtualization because you are not using a
hardware serial port on your server. The only trick is getting the
right pin-out between your serial device and the Moxa (which uses
RJ-45 jacks), but Moxa has decent documentation.
