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.
