A list of standard arguments to an external tcp handler program. A positive prefix argument always enables this mode. A negative prefix argument always disables this mode. Invoking this command with no prefix toggles the current state of the mode. Returns a subprocess-object to represent the connection.
NAME is name for process.
It is modified if necessary to make it unique. Process output goes at end of that buffer, unless you specify an output stream or filter function to handle the output. Third arg is name of the host to connect to, or its IP address.
