HBS:Handshake Bulk Parameter Set Send Indicates a parameter set image send message using
handshake mode. The parameter set to be transferred is divided into multiple packets when it is greater
than a prescribed size. The packets are transferred in accordance with handshake mode.
EXI:Extend Interval During a dump session, message sent by a devices that should send the next
message to tell a device waiting for the next message to extend the message interval. Receipt of this
message causes the message wait elapsed time to reset to 0.
SBS:Start of Bulk Dump Session This message is sent to both devices to start a session to transfer
a series of parameter sets using one-way protocol or handshake protocol. The protocol used during the
session and the data transfer direction is determined in accordance with the value of the data field. For
details, see the explanation about the data field. When there is a request to start a handshake protocol
session, the devices that receive this message return ACK after setting up to enable a session. This
message is ignored if the outlook is that a session cannot be enabled.
ACK:Acknowledge Indicates a message used by the receiver during parameter set handshake mode
transfer to convey to the sender that it is ready for send of the next packet. The cat, mem, and pset
fields indicate the value carried by the last received message.
RJC:Reject Indicates a message to convey to the other side that an ongoing parameter set one-way
mode or handshake mode send or receive session was interrupted. The cat, mem, and pset fields indicate
the value carried by the last received message.
ESS:End of Sub-session Indicates there is a message to convey to the receiving device that a one-way
mode or handshake mode serial packet transfer for sending a sub-session (one parameter set) is complete.
The cat, mem, and pset fields indicate the values in the last received message.
EBS:End of Bulk Dump Session Indicates there is a message to convey to the receiving device
that a one-way mode or handshake mode serial parameter set transfer session send, which was launched
by some operation, is complete. The cat, mem, and pset fields indicate the values in the last received
message.
ERR:Error This message is sent to a device that sent a message during a parameter set transfer
session using handshake protocol bulk dump, when the device that received the message encounters
some communication problem. The generated error type depends on the value in the data field. For
details, see the explanation about the data field.
