# Introduction

IMS is a command introduced with MSNP3.

It is a Notification Server command, without either a request or response payload.

It enables or disables switchboard access without modifying the user's current status.

# Client/Request

IMS TrID [ ON | OFF ]

# Server/Response

IMS TrID 0 [ ON | OFF ]

Where 0 has an unknown purpose. Rumored to be a timeout of some kind. [TODO: Please confirm this.]

# Examples

# Turning Switchboard access on

C: IMS 1 ON
S: IMS 1 0 ON

# Turning Switchboard access off

C: IMS 2 OFF
S: IMS 2 0 OFF

# Invalid argument

NOTE: There is no defined behaviour for this command specifically.

C: IMS 3 TOMORROW

Server disconnects client.

# Known changes

• Removed in MSNP24... probably? Who really knows... Only WebTV supported it, which only has MSNP3, MSNP6 and MSNP8.
