MATLAB serial timeout handling.

A have a "default"-configured serial port. How do I implement timeout error handling?
If I do something like this:
try
fread(SerialObject, 1, 'uint8');
catch err
myError(err)
end
it does not read that as an error (never executes catch block).
What is the proper way to handle it in this situation?

The Timeout is a warning and hence you are unable to catch it. Searching a little, I found a couple of references that might be helpful:

May be something like this:
lastwarn('');
try
fread(s)
if(~isempty(lastwarn))
error(lastwarn)
end
catch err
err
end

Use the ErrorFcn callback http://www.mathworks.com/help/releases/R2011a/techdoc/matlab_external/timeout.html
