B.1.6 Priority Data Reception
Assuming the BSC 2780/3780 software has the RVI handling option (Section 6.25 on
page 179) configured for continue, if the BSC 2780/3780 software receives a reverse
interrupt during transmission, the message transmission finishes normally, and an RVI
received code is returned in the error field of the data acknowledgment. The
BSC 2780/3780 software then sends EOT to reverse the line and prepares to receive the
priority data message. After the priority message has been received, the BSC 2780/3780
software continues transmission by sending the next message. In Figure B–8, the
BSC 2780/3780 software has the RVI handling option configured for continue, and a
priority message interrupts a transmission sequence of two messages.
