Working serial port.

I have a working serial interface sitting on a breadboard in my lab.  
One big note:  You must have some sort of reset circuit for the UART.  A 
simple power on will not suffice, the Actiontec will not see it.

The circuit I'm currently working with is a duplication of what is on 
the "official" daughter card.  If I get a chance this evening, I'll 
re-wire it to follow Bruce's schematic and verify that.

Bruce:  In answer to your "Why attach a GPS?" question.  I'm going to 
turn one of these units into a time server for my network.
