6.1.5 Drive address
The drive only acts on messages received that contain a drive address if
the whole drive address or drive group address match the whole
address or the group address in the message, or if the address in the
message is 0 (i.e. a global message). Global or group addressing allows
data to be written to more than one drive with one command. The drive
does not give a response to a global or group write message. Although it
is possible to perform a global or group read, this would result in
messages crashing if more than one drive responds to the command.
2. The command is aborted because the two digits for drive address 1
st
digit, drive address 2
nd
digit, menu number or parameter number are
not the same as each other.
3. EOT is received.
4. A character other than NAK, ACK, BS or STX is sent as a short
command.
5. A character other than ENQ is sent at the end of a read command.
The following short commands can be used:
NAK Not acknowledge (Ctl U)
This is the same as requesting the value of the last parameter to be read
or written to. The response is the same as for a normal read.
ACK Acknowledge (Ctl F)
This is the same as requesting the value of the parameter after the last
parameter to be read or written to. The response is the same as for a
normal read.
BS Back space (Ctl H)
This is the same as requesting the value of the parameter before the last
parameter to be read or written to. The response is the same as for a
normal read.
the last read or write.
All the short commands will only read from the drive or write to the drive
if a valid address has already been sent to the drive in a previous
command. The address is registered as being valid once a read or write
command has been completed provide the address was valid for the
drive even if the parameter does not exist. The valid address is
