BSC Programmer’s Guide
Caution
With larger transparent 2780 records (such that only one record
fits into a transmission block), the BSC 2780/3780 software
receives the block as:
This is exactly the same format as a 3780 transparent data block,
and is therefore sent to the client as transparent data (
dlRead
pOptArgs.usProtCommand
field set to DLI_PROT_SEND_TRANS_DATA).
This problem can possibly be avoided by setting the
BSC 2780/3780 software transmission block size large enough to
hold more than one transparent 2780 record.
5.5.2 Error, Confirmation, and Acknowledgment Responses
Ta ble 5 –12 lists the possible BSC 2780/3780 error, confirmation, and acknowledgment
response codes returned in the
dlRead pOptArgs.usProtCommand field. All of the
responses, as well as the
DLI_PROT_RESP_ERROR error report, can return an error code in
the
dlRead pOptArgs.iICPStatus field to indicate failure.
5.5.3 Reports in Response to dlWrite Information Requests
After issuing a dlWrite information request (Section 5.4.2), you must issue a dlRead
request to receive the report information. The reports are listed in Tabl e 5–1 2.
