Re: [node-red] Carriage Return vis Serial Node

[Nicholas O'Leary]

Hi Justin,

how exactly are you constructing the payload you want to send to the Serial node?

Good afternoon all,

I have an old embedded Motorola 68000 which I have connected to using the Serial Port Node.  I am able to send information to it but, it doesnt like any form of carriage return.

I would presume I am firing over the commands in ascii but the "\n" just gets added to the text and the processor does nothing.  Should I be approaching it differently? I am using the latest version of node and npm so I doubt its that.

Any pointers are welcome

Justin I've found with serial port that adding \n \r etc via an inject node string dosen't surfice.

Not sure if this is how your testing cmds to the device?

I pass all mine commands that need <cr> or <lf> via a function node.

msg.payload = msg.payload+"\n"; 

retrun msg;

//\r - Carriage Return   0x0D - 13

//\n - Line Feed          0x0A  - 10

Thanks for this !

Should this be added as a bug?

I also used the Injector to send a string value of "test\n" but it somehow removes the newline character. 

I don't mind having a look at fixing it but I just want to make sure this is an issue vs me using the wrong workflow.
