Hi,
I need to pass an external variable (a serial object to be
precise) to make it visible "inside a GUI".
What I want to do is gathering data from a serial port
after pressing a GUI button. The serial object is opened in
workspace.

I've got GUI generated in Guide. I tried to modify the
first (opening function) as:
function varargout = gui(s1,varargin) %s1-serial object
and send s1 from workspace

But when the start_Callback procedure executes after
pressing button s1 suddenly changes from seial object to a
"Start_Callback" string (???) and the variable becomes
useless.

I'm not familiar with all these weird callbacks and Matlab
procedure starts.

Anyone has an idea how to do this?
