connect) with the TROL as the passed parameter. These modules will allow the connection to complete and complete the buffer size, least common multiple, minimum byte count, and file mode negotiations as detailed in the BFX general design specification. 3. Upon completion of connection negotiation, RCV allocates the requested number of buffers and begins the transfer process. It uses a multiple buffering technique to overlap NETEX processing of the incoming record with the file writes performed by the block module. Figure 24 on page 83 shows the normal flow of data transfer 4. Whenever the block module is called to write a block received from NETEX, the block module may return with a message. The message will be sent to the SND control module in the other application, and its contents will be placed on the SYSPRINT log files of both applications. If the message indicates an abnormal end of transfer, RCV will send the message and wait for a disconnect indication from the other BFX to indicate acknowledgement of the error. 5. When an end of information delimiter is received from the remote BFX, RCV will call the block and record modules with the EOI indication. Upon return, it will free the buffers allocated in step 2 and will return to the module that called RCV. Page 82 Appendix B: BFX Internal Summary MAN-REF-H211-05
