When I execute Mack Data programming, why do I receive a warning “Other applications using the com port will probably not work properly while this application is running”?
A. This is a warning that when Mack Data programming is running, you cannot run any other VCADS operations. This is because Mack Data programming uses it own communication method to communicate with the systems, not the PTT communication method. When Mack Data programming is terminated, other VCADS operations will run normally.
