[Boatanchors] Calling Smart People- DS-1077 Oscillator

[David Stinson]

To the many people smarter than me on computers and
itty-bitty chips:

Here's a Maxim DS-1077 Programmable Oscillator
I want to use in a boatanchor project:

"The DS1077 features a 2-wire serial interface that allows in-circuit 
on-the-fly programming of the programmable prescalers (P0 & P1) and divider 
(N) with the desired values being stored in NV (EEPROM) memory."

The datasheets have lots of good info, but as always the writers
make assumptions that I'm smarter than I am.
Programming I can figure-out.... I think.
They've got some published "C" code and there's bound
to be a freeware compiler out there.

What I need to know:
I have a computer with an RS-232 port.
I have a chip with two pins.
Someone please draw me a hardware diagram of how
I'm supposed to hook these two together.
