warning in serial properties

I created a code like this

and I have a problem that the serial function is not supported in matlab 2024, if I want to change to the matlab 2024 version how will the code be?

function [sphandle] = Dataserialport(comPortNum, bufferSize)

availablePorts = serialportlist;

if ~isempty(availablePorts)

disp('Serial port(s) already open. Re-initializing...');

end

comPortString = ['COM' num2str(comPortNum)];

sphandle = serial(comPortString,'BaudRate',921600);

set(sphandle,'Terminator', 'LF');

set(sphandle,'InputBufferSize', bufferSize);

set(sphandle,'Timeout',10);

set(sphandle,'ErrorFcn',@dispError);

fopen(sphandle);

end

function [sphandle] = Controlserialport(comPortNum,~)

comPortString = ['COM' num2str(comPortNum)];

sphandle = serial(comPortString,'BaudRate',115200);

set(sphandle,'Parity','none') ;

set(sphandle,'Terminator','LF');

fopen(sphandle);

end

Hi Rangga,

Instead of serial function, you can try the serialport function. Refer to the documentation link: https://www.mathworks.com/help/matlab/ref/serialport.html

If you look in the help, it will tell you. Use serialport instead. I figure you can figure out how to change your code as well as, or better than, I can now that you know the new function to use.

help serial

 SERIAL Construct serial port object.
 
    SERIAL will be removed in a future release. Use serialport instead.
 
    S = SERIAL('PORT') constructs a serial port object associated with
    port, PORT. If PORT does not exist or is in use you will not be able
    to connect the serial port object to the device.
 
    In order to communicate with the device, the object must be connected
    to the serial port with the FOPEN function.
 
    When the serial port object is constructed, the object's Status property
    is closed. Once the object is connected to the serial port with the
    FOPEN function, the Status property is configured to open. Only one serial
    port object may be connected to a serial port at a time.
 
    S = SERIAL('PORT','P1',V1,'P2',V2,...) constructs a serial port object
    associated with port, PORT, and with the specified property values. If
    an invalid property name or property value is specified the object will
    not be created.
 
    Note that the property value pairs can be in any format supported by
    the SET function, i.e., param-value string pairs, structures, and
    param-value cell array pairs.
