MODE command can now be used for new user or channel modes (see later sections). In addition, the special syntax "MODE ISIRCX" can be used to help clients find out whether a server supports IRCX prior to logging into the server.
Syntax:
MODE ISIRCX
None in this context (checking IRCX status). For a full list of the original modes and parameters, see RFC 1459 (IRC).
The ISIRCX mode (must be in capital letters) is only functional before the user has registered with the server. IRCX servers respond with IRCRPL_IRCX and non-IRCX servers should return an error code. This allows unregistered users to query whether the server supports IRCX.
See RFC1459 for more details on the original MODE command and its parameters.

This command should only be used to see if the server supports IRCX. It should not enable IRCX. | |
