I want to impliment a PC-based data logger for my home energy usage by
measuring my total current, voltage, and power readings at my main
I know there are products that do this and have various read-outs and
data logging capability.
I don't want a readout, and I don't want data logging capabilities.
Do any modules or devices exist where I can attach a couple of coils to
measure current on my 2 hot leads and three wire connections to measure
my 2-phase 220 VAC service, and generates numeric data I can read via
serial interface by a PC with a time resolution of my choosing?

Radio Shack used to make a multimeter with RS-232 output.

A data logger without data logging capabilities

I would have thought that much was clear.
I did say "pc-based data logger".
You went too far out of your way to edit my question to make it look
like a joke or a paradox.
