Protocols/MSNP/Reference/CommandTable

This table shows which commands are supported for each server role, protocol version, and how their syntax has changed over time.

For a table showing how protocol support has varied with client version, see the Protocol Table article.

Note that all Dispatch server commands are shared by Notification servers. For brevity they are not duplicated in this table.

The MSNP2 column lists commands seen exchanged between MSNP2 clients and servers and is not limited to only the commands listed in the IETF Draft specification of the protocol.
