International Morse Code

Morse Code is a binary code for the transmission of verbal messages, devised during the 1830s by Samuel Morse. Each letter of the alphabet, numeral, and punctuation mark was assigned a distinctive combination of (short) dots and (long) dashes. The most famous combination of which is probably the distress call, SOS ..._ _ _....

In Morse code, timing is important to ensure that a coherent message is recieved. The actual length of a dot can be as long as you like, but obviously it should be short enough that messages can be sent quickly and long enough to be heard over great distances. Once this standard unit of time has been established, a dash should last three times as long as a dot. The pause between individual dots and dashes should take as long as a single dot, the pause between two characters should take as long as a dash and the pause between two words should be twice as long as a dash (six times as long as a dot).
