Is there any software still being maintained for running a CW beacon-
like TX in command line Linux?

I am looking for something that could use a serial or parallel port to
send any specified text file, which would make it capable of sending
dynamically generated content (acquired or mailed-in and written to
text).

I saw
- cwbeacon, which seems self-contained, scriptable (in the above
sense), but extremely old, unsupported, not included in any current
repository;
- cwdaemon for UDP to port keying, where UDP might either simplify
things OR be an unnecessary passage;
- unixcw, which is alleged to port-key as an "option" - but I can't
see it..

Is this all? Is there a howto I missed? Is such CLI capability hidden
into any GUI app - e.g. as in the vlc-nox player?
