I doubt, it is related to > `open-network-stream' and `notifications-get-capabilities'. It's related to open-network-stream. The capabilities-related options are generic, intended to work with a variety of protocols. The general idea is that many application protocols have optional features, and a way for the client to ask the server "Which features do you support?". This is what the Elisp documentation refers to as its capabilities. You specify the command used to get the list of capabilities in the :cabability-command option. -- Barry Margolin, barmar@alum.mit.edu Arlington, MA *** PLEASE post questions in newsgroups, not directly to me ***
