Semaphore is/was a means of visual signaling that encoded individual letters, numbers and spaces in poses the sender struck, usually while holding flags (sometimes, the user manipulated a machine with larger mechanical arms).
It was primarily used in the late 1800s through the mid 1900s between ships, but its first use was often in relays between towers (by a similar, but different system) in the UK to transmit commodities prices across great distances.
