I am trying to build the temp circuit for the 54G and am having some issues.  Does anyone have a pointer to a 1 wire interface for RS-232.  It could very well be my construction, I'm going to redo it, but I'd like to try a different interface if available.

I have the following implemented under OpenWrt on a Raspi:

It should work fine on a linksys gpio port, assuming the drivers are working/available. I'm building a controller to make salt water, change it out, and maintain levels in a 120 gal tank.

Here's another schematic of a temperature sensor I've implemented on a remote node:

The ipCam is instrumental to the operations and access ;) .
