Hog-Morse

The term was current in the United States during the period when American Morse code was still in use.

With American Morse it was far more difficult to avoid timing errors, because there were more symbol timings than there are in International Morse and some were difficult to distinguish because of their closeness; International Code has only two symbols, dots ( ▄ ) and dashes ( ▄▄▄ ), but the American code had three lengths of dash and two lengths of spaces between dots.

[1][2] A frequently quoted, but possibly apocryphal, story from the historical period concerns the similarity of L ( ▄▄▄▄ ) and T ( ▄▄ ) in the American code.

A company in Richmond, Virginia received a request for quotation for a load of UNDRESSED STAVES (rough sawn wood intended for the manufacture of barrels), but the telegraph operator had sent instead of thus sending an order for UNDRESSED SLAVES.

The company replied reminding the customer that slavery had been abolished.
