Struggling to answer your questions - at the moment the first of my trial USB scanners comes tomorrow - I assumed it was only a reader and therefore could not accept data
I had thought that if I knew the port ID (hence my original question) I could access the data with FGETS() commands - and do this in a loop - am I wrong to do it this way?
