Queries whether or not the server supports the Extended RFC1459 protocol (IRCX). Server response is same as for IRCX message.

Use ISIRCX after logging into the server.

Syntax:

ISIRCX

Example

Example 3.12. Check the server's IRCX support on a server that does not support authentication, before the user has enabled IRCX

Client: ISIRCX
Server: :<server> 800 <nick> 0 0 ANON 512 *

	Editor's Note
	This example was not in the IRCX draft. I have added it to clarify the differences between IRCX and MODE ISIRCX / ISIRCX.
