    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!
