B.1.1 BSC 2780/3780 Software Initialization
After downloading the software to the ICP, issue a dlOpen request. If the cfgLink and
enable DLI configuration parameters are set to “no,” an optional Set ICP Message Buffer
Size command (Section 5.4.1.3 on page 119) can be issued. If you do not issue the mes-
sage buffer command, the size defaults to 1024 bytes. When the
cfgLink and enable DLI
configuration parameters are set to “yes” (their default values), the DLI automatically
configures the message buffer size during
dlOpen, using the value supplied in the
msgBlkSize parameter (page 192).
Figure B–1 shows the download and buffer configuration sequence.
