it's solved. I've succeeded in reading the EZO RTD, EZO pH, and EZO FLO Stamps.

Where I struggle now is multiple byte command like 'Clear' to zero out the flow totalizer on the EZO FLO stamp. I'll have the same issues when I go to calibrate. Watch that thread that I referenced, as that's probably where I'll place my answers.
