Hog-Morse For instance, the international code has only two symbols, dots and dashes, but the American code has several lengths of dash. There is a distinction between "L" () and "T" (). Also, in the international code the space between symbols within a character is always the same, but American Morse has two different spaces. The letters "S" (), "C" (), and "R" () all consist of three dots, but the timing is different in each case. A frequently quoted, but possibly apocryphal, story from the historical period concerns the similarity of "L" and "T" in the American code. A company
Prosigns for Morse code codes such as Baudot or ASCII. The development of prosigns began in the 1860s for wired telegraphy. They are distinguished from common Morse abbreviations. Since Morse code communication preceded voice communications by several decades, many of the much older Morse prosigns have exact equivalent procedure "words" for use in the more recent radio telephony (voice). Prosigns may be represented in printed material either by a sequence of dots and dashes, or by a sequence of letters, which, if sent without the normal inter-character spacing (concatenated), correspond to the prosign symbol. There are at least three methods used to represent Morse
