* Calibration data will not be saved if:
1. Calibration was not unlocked with :CODE command.
2. Invalid data exists. (For example, cal step failed or was aborted.)
3. Incomplete number of cal steps were performed.
4. Calibration was not performed in the proper sequence.

Description
Calibration subsystem.
Cal commands protected by password.
Unlock cal; changes code if cal is already unlocked. (Default
code: KI002306.)
Query number of times 2306 has been calibrated.
Program calibration year, month, day.
Query calibration year, month, day.
Initiate calibration (must be sent before other cal steps).
Save calibration data to EEPROM.*
