Early communication systems simply indicated by lack of a response that communication was not made or that an error occurred. More sophisticated systems would indicate in response that a type of error prevented proper communication. Here, a printed message is provided detailing the error and the data stream preceding the error indication, so the operator may precisely understand what occurred.
