Serial.print is is most of the time used as a debugging tool, and with limited resources it is even more important to have the most lighweight solution for this task.

### Code size and timing comparison
### Code size and timing comparison
Code size has been obtained by calling one function at a time, compiler under the usual -0s mode. Size is the difference with the empty file size. TerSer.h can of course be used with setup() and loop(). It add the ~300 bytes Arduino initializations.

Execution time has been measured with a Nop replacing the SendCar function. The time depends on the baud rate, ~1 ms per character displayed at 9600 bits/s.
