A great application. Just one question ... in the MATLAB version of tcpip in the instrument control toolbox, there is a parameter called 'OutputBufferSize'. There does not seem to be any kind of analogous parameter for this package. Is the OutputBufferSize dynamically sized or is there a fixed value that I should know about? When responding, please consider me to be a beginner when it comes to TCPIP ... a 'tcpip for dummies' response would be appreciated :)
