opening of serial port

[jsulm]

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

Ok but still it is not working when I am using the single open function.

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

[Nimika]

@mrjj
Oh sorry by mistake I have written that but I am using ttyM0 only.

[mrjj]

@Nimika
Ok. Just checking.

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

[Nimika]

@mrjj
Its not working with any case.

[mrjj]

@Nimika

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]

@jsulm
Well I have checked all the specifications still let me check it again.

@mrjj
What do you mean by "monday one and broken"??
Please clarify it thank you.

[jsulm]

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

[Nimika]

@jsulm
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 ?

[Nimika]

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!
