This practice ensures that the sequence number variables for all secondary stations
receiving a broadcast remain aligned during the broadcast.
When the client application sends more than one DLI_PROT_SEND_NORM_DATA packet with
selective or global broadcast addressing indicated, it should also set the more data indi-
cator in the
iProtModifier field for each data packet (except the last). This prevents the
ICP from reverting to normal polling procedures prematurely. However, if the client
application fails to indicate the final data packet, the ICP waits one to two seconds
beyond the end of the broadcast before reverting to normal polling procedures.
When the client sends DLI_PROT_SEND_UNNUMBERED_DATA packets with selective or global
broadcast addressing indicated, the ICP neither resets the addressed stations nor sup-
presses secondary I-frame responses. Thus,
DLI_PROT_SEND_UNNUMBERED_DATA packet
broadcasts may be interleaved with singly addressed I-frames without causing stations
to be reset.
