raspi 2 no serial response MRL version 1.0.119

I am able to run version 1.0.099 MRL services on my Raspi 2.

With version 1.0.119 I can not set up the serial connections to my arduinos.

e.g. head.arduino - I set my mega 2580 arduino

head.arduino.serial: I select my port /dev/ttyACM1 or ACM0  but get only "no response"

Hi Juerg, Did you uploaded

Hi Juerg,

Did you uploaded the sketch " MRLComm.ino " in your arduino mega ?

PS : it's arduino mega 2560, not 2580
