Matlab GUI: Reading from Serial port and showing in different listboxes at the same time

I am working with serial port and multiple list boxes to read data in serial port. The listboxes are used to read specific data (suppose the data is coming from 3 different sources, so I have 3 listboxes).
Now the problem:
I want to read all the data separately and continuously. I mean, when I am clicking one listbox (e.g. listbox#2) after reading listbox#1's data, the listbox#1 automatically stops, so again I need to click listbox#1 to read the data for listbox#1. But I want to get the data continuously in all the listboxes without clicking (clicking for first time to initializing) every time. How can I achieve this? I have tried timer function but it shows following error: Error while evaluating TimerFcn for timer 'timer-1'.
Sample code:
function main_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
handles.timer = timer(...
'ExecutionMode', 'fixedRate', ... % Run timer repeatedly
'Period', 1, ... % Initial period is 1 sec.
'TimerFcn', {@listbox1_Callback, handles});
guidata(hObject, handles);
function listbox1_Callback(hObject, eventdata, handles)
%serConn is the connection to COM port
out = fscanf(handles.serConn);
string = 'degrees1';
t=1;
while(t < 15)
if strncmp(out,string,8)
rxtext = out(14:15);
currList = get(handles.listbox, 'String');
set(handles.listbox,'String',...
[currList ; [temp]]);
end
pause(5);
t = t+1;
end
end
