You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: CliffRightSignalStrengthRoomba.m
    path of file: ./repos/robotics-toolbox-matlab/interfaces/@Create
    
    the code of the file until where you have to start completion: function [Signal] = CliffRightSignalStrengthRoomba(serPort);
%[Signal] = CliffRightSignalStrengthRoomba(serPort)
%Displays the strength of the right cliff sensor's signal.
%Ranges between 0-100 percent signal

%Initialize preliminary return values

try
    
%Flush Buffer    
N = serPort.BytesAvailable();
while(N~=0) 
fread(serPort,N);
N = serPort.BytesAvailable();
