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

        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 "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!
