What about trying it?
x = fgetl(serial);
disp(class(x));
Looking in "doc serial/fgetl" it looks like it is a CHAR.

Possibly upon timeout or end-of-file it would return a different class of data such as the number -1 or an empty numeric array. You would need to test this case.

I've read http://www.mathworks.com/help/techdoc/ref/serial.fgetl.html and find the description of the outputs too vague. "[tline,count,msg] = fgetl(obj)" is helpful to detect timeouts and errors, but what is "msg" in case of success exactly?
@Safiullah Khan: The documentation is not clear enough in this point. Please send an enhancement request to TMW.
