 - Start by calling `TF_Init()` with `TF_MASTER` or `TF_SLAVE` as the argument
 - Implement `TF_WriteImpl()` - declared at the bottom of the header file as `extern`.
   This function is used by `TF_Send()` and others to write bytes to your UART (or other physical layer).
-  Presently, always a full frame is sent to this function.
+  A frame can be sent in it's entirety, or in multiple parts, depending on its size.
 - If you wish to use timeouts, periodically call `TF_Tick()`. The calling period determines 
   the length of 1 tick. This is used to time-out the parser in case it gets stuck 
   in a bad state (such as receiving a partial frame) and can also time-out ID listeners.

 They try to simulate real TinyFrame behavior in an embedded system with asynchronous 
 Rx and Tx. If you can't run the demos, the source files are still good as examples.
