morsen.

morsemorse: [19] People had for some years been experimenting with the magnetic telegraph, but it was the American inventor Samuel Morse (1791–1872) who in 1836 produced the first workable system. And with his assistant Alexander Bain he devised a set of dots and dashes representing letters and numbers which could be used for transmitting messages, and which came to be known as the Morse code. In the first half of the 20th century morse was also used as a verb: ‘It can be used for Morsing instructions about breakfast to the cook’, Punch 31 March 1920.
