A protocol for communicating messages between a manager for a computer system and a remote facility asynchronously connected with the system manager and a method for exchanging messages using the protocol. The protocol determines whether the system manager is ready to exchange messages with the remote facility, determines whether the remote facility is ready to exchange messages with the system manager and exchanges messages between the system manager and the remote facility. To exchange messages, a command message which includes a first field for identifying a command transmitted by the command message and a second field for identifying the command message is transmitted. In response, a command reply message which includes a first field for identifying the command to which the command reply message is in response to, a second field for matching the command response message to the command message and a third field for transmitting a response to the command message is transmitted.
