Using HDLC/LAP-B (ABM) Protocol
Request Specific Processing
Chapter 334
Control Codes
This protocol allows the following Control Codes:
5 CW_STATS Send ST25L2STAT status message
This control write triggers the protocol to send a
ST25L2STAT status message. For the format of this
message, see the section on “Status and Error
Messages”. Control length must be zero.
6 CW_REVCODE Send ST25REVCD status message
This control write triggers the protocol to send a
ST25REVCD status message. For the format of this
message, see the section on “Status and Error
Messages”. Control length must be zero.
7 CW_TIMERS Set timers
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.
