4.2.2.26 "Set Minimum Track Rate" command
This command sets the minimum track rate that is allowed to be set with a Proprietary Track (0x30), Motion Activated
Proprietary Track (0x34) or Proprietary Dock Mode (0x35).
The minimum track that can be set in any case with one of the above commands is "2" which is interpreted as 2.5
minutes (all other values that may be sent are interpreted as the actual number of minutes).
This command will not be NAKed for values < 2 but setting this "minimum" value to less than 2 shall simply enforce the
absolute minimum of 2.
The factory value for this shall be "0".
