% fibreobjdisconnectsilent(serialObject) terminates communication with the
% FOR, given serialObject as a valid FOR serial object (generated by
% fibreobj). It disconnects without sending ANY commands to the FOR.

% e.g. fibreobjdisconnectsilent(serialObject(9)) - terminates communication
% with the FOR attached to COM9.

% Range:

% serialObject = valid serial port object
