How can I send data to a different serial port when a callback event occurs on another serial port?

I am trying to send data via USB serial port when an event occurs on another serial port.
I am getting the following warning:
Warning: The BytesAvailableFcn is being disabled. To enable the callback property either connect to the hardware with FOPEN or set the BytesAvailableFcn property.

s1 = serial('COM1', .....);
s2 = serial('COM7', .....);
set(s1, 'BytesAvailableFcn', @(src, evt) fwrite(s2, fread(s1, s1.BytesAvailable)) );
fopen(s2);
fopen(s1);

I'm seeing the same error message, but I am trying to use the serial object in the callback. If you happened to find a solution, please share it here. I'll keep looking around.
