Driver to decode tide heights as transmitted by a Digitrans radio link, such as the one used by PAH (Port Autonome du Havre) in France.
A complete data message contains 48 sequences (16 channels times 3).
Some channels contain tide heights, while other channels contain wind speed or direction, or pressure.

Data is timetagged when a new "M0" sequence is received.
Data is updated when the maximum channel, entered in Database Setup, is received.
The channel that is decoded corresponds with the slot of a tide observation.
Tide Observation Slot.
Enter channel number to be decoded as tide observation slot number.
Available slot numbers are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and : , ; , <, =, >, ?, or 10, 11, 12, 13, 14, 15. (":" equal to "10", etc.).
Drivers IO Notes
Command line parameters SOL1 and SOL2 can be used to decode a slightly different format.
The SOL1 and SOL2 formats consist of 3 sequences per channel, the first one containing BCD digit of meters, the second one decimeters and the third one centimeters.
However, these formats have not been tested with real data.
