3.4.2.2 Request Configuration Report
Use the dlWrite function with the pOptArgs.usProtCommand field set to
DLI_PROT_GET_LINK_CFG to request the current configuration option settings for a link.
The
dlRead configuration report response (the pOptArgs.usProtCommand field is set to
DLI_PROT_GET_LINK_CFG by the DLI) consists of a sequence of 16-bit word pairs containing
the option number in the first word and the option setting in the second. The report
format is identical to that used by the
dlWrite Configure Link command (Figure 3–2 on
page 60).
3.4.2.3 Request Statistics Report
Use the dlWrite function with the pOptArgs.usProtCommand field set to
DLI_PROT_GET_STATISTICS_REPORT to request link statistics. The BSC 3270 software main-
tains a set of link statistics. The report consists of 10 words (20 bytes) of statistics. The
first six of these words contain link statistics. Link statistics keep track of events specific
to a physical link on the communications server. The last four words of the report con-
tain statistics for a particular control unit. To request a specific control unit, place the
control unit number (0–31) in the MSB of the
pOptArgs.usProtCircuitID field. Use a CU
number of 32 to request statistics for all control units.
The format of the dlRead statistics report response (the pOptArgs.usProtCommand field is
set to
DLI_PROT_GET_STATISTICS_REPORT by the DLI) is shown in Ta ble 3 –7.
