Error while evaluating UIControl Callback

[Naga Venkata Kishore Akkala]

I am having a similar error and couldn't open picgui

"Error using serial/fopen (line 72) Open failed: Cannot connect to the COM3 port. Possible reasons are another application is connected to the port or the port does not exist.

Error in picgui

Error in gui_mainfcn (line 95) feval(varargin{:});

Error in picgui

Error while evaluating UIControl Callback."

Can any one help us with this issue?

@Naga: Please open a new thread for a new problem. Thanks. Then do not forget to explain, if you have considered the error message already: "another application is connected to the port or the port does not exist".

As far as I'm aware there's no script, function, class, or app named picgui in any MathWorks products, nor do I find any references to it when I search the documentation or the File Exchange. From where did you obtain this code?
