If anyone has any photos or diagrams, please upload them to the wiki (NOT link to an external image) and add them to this page.
For those interested: (--------- is nearest board edge)
Buffalo WBR2-G54(S)

The serial port runs at 115200 baud, 8 bits, no parity, 1 stop bit using ANSI terminal emulation.
Buffalo WHR-HP-G54
Connector J1
| rx o | tx o | gnd o | vcc o | -------------
The serial port runs at 115200 baud, 8 bits, no parity, 1 stop bit using ANSI terminal emulation. Levels are not RS232 voltage levels, but +3.3V TTL logic. Use level shifter (Max232/Max3232/DS275 etc.) to correct this. Also a USB to serial phone cable will work in most cases. A cable with a Prolific 2303 works fine to access the router as a device (Eg. to get a bootloader commandline). It does not work in host mode to control USB devices. The VCC pin puts out 3.3V.

Airlink AR430W
Dynex DX-NRUTER
Dlink DIR-300 revb
NOTE: RevB is completely different hardware, based on Ralink RT3050 SoC. The serial port runs at 57600 baud, 8 bits, no parity, 1 stop bit using ANSI terminal emulation. Levels are not RS232 voltage levels, but +3.3V TTL logic. Use an interface converter chip (Max232/Max3232/DS275 etc.) to connect to standard RS-232.
TP-Link TL-WR941ND ver.3

You have to short R356, if not, the TX will not going to work.
