It's probably a JTAG port. However, you need a level shifter to connect it to your computer.

Here is some info I got from the OpenWrt project.

3CRWER200-75

* Processor: Atheros AR2315 SOC, MIPS 4KC, 180MHz
* SDRAM: 16MB
* Flash: 4MB
* Network: 4 LAN + 1 WAN autosensing 10BASE-T/100BASE-TX port.

It's propably either JTAG or TTL-level serial, either way you need JTAG-cable or max-232 or equivalent serial "converter"...

I also have one of these routers and want to learn some stuff about using serial connection, so I got myself a cable and now I want to connect it to the router.

Has anyone figured out which of these 9 pins is which?
