Parameters

dl_primitive

DL_HP_INFO_ACK

dl_mem_fails

number of memory allocations that have failed.

dl_queue_fails

number of times that the DLS provider was unable to forward a message because the queue was full.

dl_ack_to

length of the ACK timeout in tenths of a second. The ACK timeout determines the length of time that LLC Type 2 will wait for an acknowledgment of any outstanding I PDUs or for a response to a U PDU before attempting to force a response.

dl_p_to

length of the P timeout in tenths of a second. The P timeout determines the length of time that LLC Type 2, after sending a command with the P bit set to 1, will wait for a response with the F bit set to 1 before attempting to force a response.

dl_rej_to

length of the REJ timeout in tenths of a second. The REJ timeout determines the length of time that LLC Type 2 will wait for a response to a REJ PDU before attempting to force a response.
