matlab GUI: writing to a field in a different GUI

HI, I have a GUI which opens a serial communication. When a message is recieved, a special interrupt function is called which handles all the incoming messages. For example:

• if i get 01 0A i write to box X the value A
• if i get 02 0B i write to box Y the value B

i call this function like this:

handles.SerPIC.BytesAvailableFcn = @(src,event) intcon1(src,event,handles.input1,handles.input2);

if user presses a button, a secong GUI opens and does some things

Now, lets say that i want to write B to a box Z which is in GUI number 2. How can i do that? The problem (as i see it) is my interrupt function needs to get before hand all inputs, but i make the BOX Z handle visible only after....

Thanks. i was able to pass handles through setappdata(0,'name',gcf) and reading it on the other side
