[OpenWrt-Users] serial ports on linksys WRT54GL?

[Ivo van Geel]

Hi Robert,

The WRT54GL is basically version 4 of the WRT54G. The jumpers have been
renamed between versions of the WRT54GL or from the transition of the
WRT54G to the WRT54GL.

The 12pin connector is always the JTAG interface. The 10pin connector is
always the dual serial port. The pin numbers on each interface have
stayed the same, regardles of the jumper names.


Regards,
Ivo.
