The metre is a two-symbol alphabet — long and short, – and ‿. So is Morse: dash and dot. They are the same alphabet. This device speaks Morse in the metre's voice: short pluck for ‿, long pluck for –. Type to send; tap the key to send by hand; paste – ‿ to receive.

the long/short alphabet (Morse, in metre glyphs)
what this is. a real, decodable communication device. the encoding is standard Morse — a genuine variable-length binary code — rendered in the metre's two durations and played on a plucked-string voice. long is held about twice as long as short, the Greek ratio, not Morse's 3:1.
what it isn't. a historical claim. Sappho had no telegraph; Morse is 1830s. the real thread is the shared abstraction — both systems carry meaning on a two-symbol alphabet of long against short. the metre and the telegraph are cousins through their code, not their century.
