Notes:
1. Brackets [ ] are used to denote optional character sets. These optional characters do not have to be included in the program message.
Do not use brackets [ ] in the program message.
2. Angle brackets < > are used to indicate parameter type. Do not use angle brackets < > in the program message.
3. Upper case characters indicate the short-form version for each command word.

(0 = locked; 1 = unlocked)
Save cal constants to EEPROM.
Download cal constants from 2001.
Send cal date to 2001.
Request cal date from 2001.
Send next due cal date to 2001.
Request next due cal date from 2001.
