You'll have to be a WHOLE lot more explicit as to what you want to do here. on x86 hardware, RJ45 ports are almost always ethernet, serial ports generally use DB9 connectors. On some other servers like Sun Sparc and IBM Power systems, RJ45 ports are sometimes used for serial console connections, but those ports are wired up to UARTs (asynchronous communication adapters) rather than ethernet network interface adapters.

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. -- Jeff
