/** | |
* Controls and reads actual measured distance from LCD bus of a Sndway SW-A40 laser distance meter. | |
* Improved version not using Arduino delay that causes random problems with serial interface. | |
* | |
* Serial control characters: | |
* | |
* ? Return identifier string. | |
* c Clears measurement results and turns off laser. | |
* Can be used as keep alive command to prevent auto power off after 150s. | |
* M Turns on device when off and triggers a measurement. |
