 to do some tasks when receiving data from MMDVMHost or NextionDriver:
 - change colors and fonts of the TA on the DMR page when it arrives.
  (TA length calculation is done in the display itsself !)
+- remove the slot number from t2.txt (since it's always 2)
 - display the GPS data (if received) in a new field (called 'GPS'),
   by copying the GPS data form the field where MMDVMHost has
   written to (t11 for GPS data from slot 2 in DMS format)
- remove the slot number from t2.txt (since it's always 2)

+The examples are there to give you an idea of what can be done.
+It is up to your imagination to go even further.
+When, for example, you want to change the text 'listening' to some
+other text, like 'RX', you just have to monitor the event status and 
+take action in the Touch Event of S0 of the corresponding page.
+Or you could hide/show pictures, switch to other pages, etc.
+   
+Check the NextionDriver program and the display layouts there to see
+ some other examples of what can be done by programming in the 
+ display. (https://github.com/on7lds/NextionDriver)

+NOTE: it might be good to *not* remove fields from the display when you do not
 need them, but make them small (i.e. 10 x 10 pixels) and put them aside:
 Give them the same font color and background color as where you put them
 OR
 Put them behind some picture: put them on top of the picture, then select the 
 picture and click the 'Bring Top' button to put it on top of all those fields
+ OR
+ set them invisible when the page is selected (with the 'vis' command) in the 
+ preinitialize event of the page

 This way, you can use the data from the fields to process them 
 as is done with the GPS data in the example.
