Solaris 7980g User Guide 185
Concatenation of Multiple Commands
Multiple commands can be issued within one Prefix/Storage sequence. Only the
Tag, SubTag, and Data fields must be repeated for each command in the sequence.
If additional commands are to be applied to the same Tag, then the new command
sequence is separated with a comma (,) and only the SubTag and Data fields of the
additional command are issued. If the additional command requires a different Tag
field, the command is separated from previous commands by a semicolon (;).
Responses
The device responds to serial commands with one of three responses:
ACK Indicates a good command which has been processed.
ENQ Indicates an invalid Tag or SubTag command.
NAK Indicates the command was good, but the Data field entry was out of
the allowable range for this Tag and SubTag combination, e.g., an
entry for a minimum message length of 100 when the field will only
accept 2 characters.
When responding, the device echoes back the command sequence with the status
character inserted directly before each of the punctuation marks (the period, excla-
mation point, comma, or semicolon) in the command.
