      Hi are you 100% sure about portname ?
      serial.setPortName("ttyM");
      I would expect a number ttyM0

          Ok. Just checking.

          Did you try with minicom or any other serial programs if it will open it ?

              Well if minicom or friends dont like it either, my guess would be

              Its brand new, you never gave anyone (user) permissions to ttyMX

              its a monday one and broken :)

                @Nimika If it still not able to open the connection then check all the connection parameters you're specifying.

                  @Nimika "made on Monday" :-)
                  Usually people are not fully operable on Monday after weekend and do more mistakes and produce more broken products :-)

                    Lol!
                    but I think I am nowhere lacking in this regard.

                      Hi,

                      Looks like you're on linux, wouldn't that be /dev/ttyM0 ?

                      One other thing: do you have the rights to access the serial port ?

                        Hello all thank you for your replies.
                        I sorted out my problem, its there in installation.
                        Now all ports are working fine.

                        @SGaist
                        Yeah I have used /dev/ttyM0 only.
                        Thank you!
