HP Advanced Communications Controllers (ACC) manual Received Data

Using HDLC/LAP-D Protocol

Request Specific Processing

7	CW_TIMERS			Set timers
				This request is only allowed for non-UI terminals. The
				protocol’s timers may be changed from their configured
				values using this control write. This request should be
				used with caution because the values configured with this
				request will not be restored if the card is reset by ZCOM.
				The control request data consists of three pairs of bytes.
				Each pair of bytes consists of a Resolution and a Value.
				The legal values for Resolution are as follows: 0 = don’t
				set, 1 = 10msec, 2 = 100msec, 3 = 1sec, 4 = 10sec.
				Note that these values are different from the values used
				for the resolutions when configuring a terminal. The
				Values are used directly. A zero Value will disable the
				timer if the resolution is non-zero.
				The first pair of bytes applies to T200, the second pair is
				ignored (should be set to zero) and the third pair apply to
				T203:
15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
T200 Resolution (0-4)								T200 Value (0-255)
0
T203 Resolution (0-4)								T203 Value (0-255)
