Where can I find the manual about socket communication with Maxima ?

No, AFAIK there is no easy way out. The output stream doesn't contain
any flag to separate good from bad. 

If I am not mistaken, errors can occur in Lisp and in Maxima, so the
string containing an error message contains either "-- an
error." (Maxima level) or "Maxima encountered a Lisp error:" (Lisp
level). 

I remember that from time to time there is a question about suppressing
error messages, but I cannot remember what came out of this discussions.
Maybe you'll find something in the list-archives.

Sorry, I can't be more helpful.
