...where argument for "m" would be either string to send, or file to parse and send. But, frankly, it would be goot enough to also allow continuous morse'ing content from other thing's stdout, and a icing on the top would be a keyboard-interactive code, where, message is transferred as soon as we push keyboard buttons (if we write faster than it sends, then, it would flash till it send everything or gets interrupted by ctrl-c etc.)

Could be something like -m -i (interactive)
