IMS

The client can ask the server to not forward any RNG and not to accept any XFR SB commands by using the IMS command. It effectively blocks all new SB connections, and therefore all new chat sessions.

Sent to server

Description

IMS trid on/off

Parameters

• trid: Transaction ID
• on/off: Either ON or OFF. ON means "please forward RNG and accept XFR commands". OFF means "please do not forward RNG and accept XFR commands".

Server returns

Description

IMS trid 0 on/off

Parameters

• trid: Transaction ID
• 0: It's unknown what it means.
• on/off: Either ON or OFF. ON means "NS will forward RNG and accept XFR commands". OFF means "NS will not forward RNG and accept XFR commands".

Example

>>> IMS 28 OFF
<<< IMS 28 0 OFF

The client requested the NS to drop incoming XFR commands, and not forward RNG commands to the client. The server responded that it will do so.

>>> IMS 29 ON
<<< IMS 29 0 ON

The client would like to be able to set up new connections to switchboards, and requests this to the server. The server responded that this is ok again.
