Just a set of semaphore flag poses for fun (as seen from receiver's side). I have seen one here, just thought I could make my own version.
C or 3 - Acknowledge / Correct
E or 5 - Error (if signaled 8 times)
J - Letters to follow
# - Numerals
repeated switch U/N - Error / Attention
Cancel is located on & glyph for lack of tools for finding right unicode 0018
Sempahore is a flag-based form of communication, used to visually communicate information over long distances.
Lower case lettes (NO CAPS LOCK REQUIRED) & the following special characters are used:
Period (.) = "Rest" in semaphore.
Pound Sign (#) = "Numbers". Since some letter symbols are also used as numbers, type in # before typing in numbers. Conversely, type "J" to indicate you're going back to letters.
Exclamation Point (!) = "Attention". Type !, when the message is important.
"X" = "Cancel". To nullify the previous message.
