This cross-reference is used to link the HL Lower Layer Parameter file (#869.2) with the HL Logical Link file. Using this x-ref you can locate the parameter associated with this link.

This field is not editable from any user option. It is used purely for display purposes in the DEVICE TYPE column of the SYSTEMS LINK MONITOR display option.

This field is not editable from any user option. It is used purely for display purposes in the STATE column of the SYSTEMS LINK MONITOR display option.

This field permits the link to be restarted by Taskman after a system reboot. If disabled, the link will not be restarted.

The queue structure relies on two queues, INcoming and OUTgoing.  This pointer is used to point to the first message in the FIFO queue.

This is the task number assigned by TaskMan when the Lower Layer Protocol is launched in the background.

This field is editable through the STOP HYBRID LLP option. When the Lower Layer Protocol is running, and this field is set to 'Y' the Lower Layer Protocol will shutdown and close the device.
