Problem with the odt notation of "configureTerminator" for serialport

2 visualizzazioni (ultimi 30 giorni)
Hi,
I do this with serial port:
sss=serialport('com1',9600)
Then, I try to configure the terminator with the dot notation:
sss.configureTerminator = 'CR'
I receive this error:
Assignment not supported because the result of method 'configureTerminator' is a temporary value.
If I do this:
>> configureTerminator(sss,'cr')
that works.
Why? I wrong something in the sintax?
All the other commnads I used like flush, write, writeline, read, etc have not shown problems with dot notation.
Tyhank you, Gianluigi

Hello Gianluigi,
From what I could understand from the documentation of 'serialport', I can see that 'configureTerminator' is an object function and not an object property which could be accessed using the dot notation through assignment. The 'configureTerminator' function would set the terminator of the device that is passed to it i.e. the serialport device.
The error also states that 'configureTerminator' is a method and not a property. That is why you are unable to configure the terminator with the dot notation.
Please refer to the following documentation for more information on 'serialport' and 'configureTerminator'.
Hope this helps!

Hi Sarthak,
sorry for the delay in my answer.
The help for any of those function is for a conventional use, not a dot notation.
However I have a news: the dot notation for configurterminator is working.
My error was to assign the terminator this way:
sss.configureTerminator = 'CR'
But the correct sintax is:
sss.configureTerminator( 'CR' )
Do you agree?
thank you gianluigi

Hi Gianluigi,
Yes, as I stated configureTerminator is an object function, which means you can call it on the object as the following and the dot notation will work
sss.configureTerminator('CR');
or use it conventionally like in the documentation shared as
configureTerminator(sss, 'CR');
Apologies for any confusions.
Cheers!
