Description
This list in item 1 contains the identifiers of all the Trace Objects which were reset. If all Trace Objects are successfully reset,
then ACKA shall be set to TRUE.

Exception
If ACKA is TRUE, then no errors were encountered, meaning all report requests were completed successfully and a zero-length
list (m = 0) shall be sent.
If some reports could not be reset, then their TRIDs shall be given in a space separated list in ERRTEXT.

10.22 Stream 18 Subsystem Control and Data — Messages exchanged between component subsystems and higher
level controllers. Compared to similar messages exchanged between equipment and host, subsystem messages are
less complex.
Stream,Function Name (Mnemonic) Direction

Description
Used in lieu of an expected reply to abort a transaction. Function 0 is defined in every stream and has the same meaning in every
stream.

Description
This message acknowledges the success of failure of the request to write attribute data to the subsystem indicated in
TARGETID.

S18,F5 Read Request (RR) S,H->E,reply
Description
The host requests the subsystem indicated in TARGETID to read information. DATASEG may be used to indicate a specific
section of data to be read. DATALENGTH is used to limit the amount of data for that section.
Structure
L,3
1. <TARGETID>
2. <DATASEG>
3. <DATALENGTH>
Exception
If DATASEG and DATALENGTH are both omitted (are zero length items) then all data is requested. If DATALENGTH only
is omitted, then all data within the indicated section is requested.
