Morse code
Summary: telegraph was first used by the United States Morse invented in 1844, it is also known as Morse code.
It consists of two basic signals and different time intervals: the short point signal "*" Reading "of" (Di); maintaining a
Given the long time signal "-" read, "A" (Da).
Interval: drops, 1t; A, 3t; between tick, 1t; between letters, 3t; between words, 5t (a custom unit time t).
Note: * denotes SMS number - indicates long signal
