‘etalk’ is an Emacs interface to the unix chatsystem called ‘talk’, among other things. That’s what this page describes.
Talk, quite like VMS’s PHONE, is an older chatting system that can be used to reach users on remote hosts, if their system is running some compatible daemon, a program serving clients. Several extended variants of the BSD flavour exist. ntalk, otalk, ytalk and GNU Talk (gtalk) at least, and the KDE project has it’s own variant too, ktalk.
Etalk in an interface to, and depends on the GNU Talk program gtalk(1), which implements protocol versions 0 and 1, and proposes 2. Several features are available only when thge GNU Talk deamon, gtalkd(8) is used. Among these are the games, sending files over the connection, auto-answer and so on.

At least for version 0.99, after loading etalk library, the Tools menu gets an entry but it doesn’t do anything. In etalk buffers
C-h doesn’t do what it usually does, but tells the other end to move her image of your point backwatrds one step… there’ll be a ^H though on the local display though.
