Could you send the internet by waving flags?
The Transmission of IP Datagrams over the Semaphore Flag Signaling System (SFSS)
An April Fools’ internet standard for sending internet data by people waving flags at each other.
Flag semaphore is the old system of signalling letters by holding two flags in different positions. This April Fools’ document describes how to send internet data that way, one flag pose at a time.
It covers how to turn bits into flag positions, how two flag-wavers start a conversation, and how they politely say goodbye. Bandwidth: limited by arm strength.
The internet, but make it semaphore.
