Omron CS1W-ETN21 operation manual Send Information 40 Bytes, Receive Information

Command/Response Reference Section 7-3

12.The number of times no window advertisement is received within the time set on the duration timer. (The duration timer sets the maximum time limit for a window advertisement to be received if the transmission window is smaller than necessary and the resend timer is not set. If no window ad- vertisement is received within the time limit, the number of segments per- mitted by the transmission window are sent. If the transmission window is set to 0, a window probe (1 octet of data) is sent before the timer restarts.)

13.The number of times no segment was sent or received within the time set on the hold timer.

14.The number of times the hold packet is resent. (Always 0.)

15.The number of times the hold packet is sent without response before the connection is cut off.
