Opens a connection to a Hyperwave server and returns a
connection index on success, or
FALSE if the connection could not be made. Each of
the arguments should be a quoted string, except for the port
number. The username and
password arguments are
optional and can be left out. In such a case no
identification with the server will be done. It is similar to
identify as user anonymous. This function returns a
connection index that is needed by other Hyperwave functions.
You can have multiple connections open at once. Keep in mind,
that the password is not encrypted.
