Re: [Maxima-discuss] How can I call Maxima functions from a language different from Common Lisp? (FFI or server/client, doesn't matter)

It's the other way round: Maxima is the *client*, not the server.

So *first* start netcat in server mode on port 1234:
nc -l 1234
(or your program, which must be a server).

*Then* start Maxima as client, with the option -s 1234 to connect to the
Server on port 1234:
maxima -s 1234

And then the server can submit maxima commands (for example you in your
terminal Window using netcat as server) and the Maxima client will
compute them and return the results.

(Can a Maxima client connect to a port on another computer? It does not
seem so...)

Yes, it would be nice, if Maxima would have the possibility to
communicate in a more computer parseable way.
