Synchronous Link Control (SLC) Programmer’s Guide

4.2 Link Category

The commands and responses in the Link category are used to enable, disable or con-

ﬁgure a speciﬁed SLC network connection. Only an application session with Master or

Control access mode can use this category.

4.2.1 Bind

The DLI_ICP_CMD_BIND command enables the SLC network connection to which the

application has obtained access. The corresponding

DLI_ICP_CMD_BIND response reports

the success or failure of the request. The header formats are detailed in Section 5.2 on

page 63.

4.2.2 Unbind

The DLI_ICP_CMD_UNBIND command disables the SLC network connection that the

application previously enabled. The corresponding

DLI_ICP_CMD_UNBIND response

reports the success or failure of the request. The header formats are detailed in

Section 5.16 on page 81.

4.2.3 Conﬁgure Link

The DLI_PROT_CFG_LINK command contains conﬁguration information as described

below for the SLC network connection associated with a speciﬁed ICP data link. The

conﬁguration can also specify SLC channels 2…7, associating an additional ICP data

link with each channel. The application writes this command to conﬁgure an SLC net-

work connection and clear its statistics. The corresponding

DLI_PROT_CFG_LINK

response reports the success or failure of the request. The DLI_PROT_CFG_LINK header

formats are detailed in Section 5.3 on page 64.

Examples of a failed conﬁguration request would be if a Master or Control client is

bound to the associated SLC network connection at the time of the request, or if the

command contains an invalid conﬁguration option.
