on the ICP, an application in the client attempting to write a control packet to the ICP
experiences delayed I/O completion, but no packet is actually lost.
3.4.4 DLI_PROT_RECV_UNFORMATTED_DATA Packet
This packet is valid only if the client has enabled ADCCP option 5 (see Section 3.4.20.2)
for the specified station and the station is in the initialization state. The ICP specifies the
usProtCommand field (DLI_PROT_RECV_UNFORMATTED_DATA), the link ID, the
usProtXParms[0] field (station ID), the usProtXParms[1] field (data size), and the data
field contents. The client has total responsibility for handling all initialization protocol
requirements.
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 frame associated with the
DLI_PROT_RECV_UNFORMATTED_DATA packet passed to the client. If bit 7 is reset to zero, no
error was detected.
3.4.5 DLI_PROT_SEND_UNFORMATTED_DATA_EOM Packet
As an option, the client may send the DLI_PROT_SEND_UNFORMATTED_DATA_EOM packet
instead of the similarly named
DLI_PROT_SEND_UNFORMATTED_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 5 (see Section 3.4.20.2).
Note that if the optional arguments in the DLI_PROT_SEND_UNFORMATTED_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.
3.4.6 DLI_PROT_SEND_EXCHANGE_ID Packet
This packet is valid only if the client has enabled ADCCP option 1 (see Section 3.4.20.2)
for the specified station and the station is not in the initialization state. The client must
