Hi all, I am confused. There are about as many interpretations for prosigns and punctuation as there are resources describing this subject. What is THE standard ? E.g. even Wikipedia (which is not supposed to be authoritative acc. to academia) has clashes between prosigns and punctuation. E.g.: See '=' and '' on: http://en.wikipedia.org/wiki/Morse_code http://en.wikipedia.org/wiki/Prosigns_for_Morse_Code So, what is the authoritative version ? (I am working on the decoder and these inconsistencies drive me crazy). tia, Peter P. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
