Hi Alexander

As per my understanding you are receiving the following warning message.

To suppress the warning message while using ‘tcpclient’ and the ‘readline’ function, MATLAB's warning management functions can be used.

For this, the first step is to find the warning identifier for the specific warning that needs to be suppressed. This can be done as follows.

w = warning('query', 'last');  %This gives the last displayed warning. As per the discussion, this is the warning that we would like to suppress.
id = w.identifier;  %Now, the warning identifier of the warning is stored in id.
warning('off', id); % The warning is suppressed here.

By executing these commands, the warning is disabled which can be seen here.

If we want the warning to be re-enabled, it can be done as follows

warning('on', id);

For more information regarding suppressing warnings, kindly refer the following documentation https://www.mathworks.com/help/matlab/matlab_prog/suppress-warnings.html

I hope this helps.
