Semaphore was invented as a visual signaling system to relay messages over long distances. It was developed to communicate with ships at sea or between different points on land where other methods of communication like smoke signals or flags were not practical. Semaphore systems used different flag positions to represent different letters or words and were widely used before the invention of the telegraph.
You would use the alphabet of the semaphore flag signaling system. See the related link for the picture of signals.
The semaphore flag signaling system was developed by Claude Chappe in France during the late 18th century. Chappe's system used a series of different flag positions to convey messages over long distances, and it was widely used for communication before the invention of the telegraph.
