Telling from the first post, being a transmitter is more complicated than being the receiver. Transmitter requires three QB64PE-only functions and two file handles! There is no "CLOSE" statement, is that statement necessary for those "_OPEN" functions?
Definitely if one of those "_OPEN" functions returns zero then it's no-go as file handle. This is not really to my interest but I should become involved as it could become real useful some day offline.
