addressing is indicated. If bit 1 is set to one and bit 2 is reset to zero, selective broadcast

addressing is indicated. If bit 1 is reset to zero and bit 2 is set to one, general broadcast

addressing is indicated.

For all stations, bit 7 in the iProtModifier field is an error indicator. Bit 7 is set to one if

the ICP detected an error during reception of the UI frame associated with the

DLI_PROT_RECV_UNNUMBERED_DATA packet passed to the client. If bit 7 is reset to zero, no

error was detected. Bit 0 and bits 3 through 6 in the

iProtModifier field are zeroed.

3.4.12 DLI_PROT_SEND_UNNUMBERED_DATA_EOM Packet

As an option, the client can send the DLI_PROT_SEND_UNNUMBERED_DATA_EOM packet

instead of the similarly named

DLI_PROT_SEND_UNNUMBERED_DATA packet to request that

the ICP respond with a corresponding

DLI_PROT_RESP_LOCAL_ACK response packet to

report transmission completion status. This packet is valid only if the client has enabled

ADCCP option 4 (see Section 3.4.20.2 on page 71).

Note that if the optional arguments in the DLI_PROT_SEND_UNNUMBERED_DATA_EOM packet

specify a link or station that is not configured or not online at the time of the request,

the ICP replies instead with a

DLI_PROT_RESP_ERROR packet.

3.4.13 DLI_PROT_SEND_SET_MULTIPNT_LIST Packet

This packet is valid only if the client has enabled ADCCP option 7 (see Section 3.4.20.2)

for the specified station operating in NRM mode and has configured each local or

remote secondary station address as a single octet. This packet is valid both in the dis-

connected state and in the information transfer state.

When extended addressing (ADCCP option 7) is enabled, a frame containing a multi-

ple octet address field may address either a single station or a list of stations. On a given

link, the client controls which interpretation is used by identifying stations that use the

second concept to implement a multipoint selective broadcast function. The

DLI_PROT_SEND_SET_MULTIPNT_LIST packet is used for this purpose.
