Semaphore Flag Signalling System
The Semaphore flag signaling system is an alphabet signalling system that uses flags in a variety of positions.
The flags are usually square, red and yellow, divided
diagonaly with the red portion in the upper hoist.
The flags are held, with arms extended to full length, in various positions.
The various different positions are like a clock face, divided into eight positions: up, down, out, high, low, for each of the left and right hands (LH and RH) .
The different combinations represent each of the letters of the alphabet.
