5.4. Status Commands
These commands deal with general interface aspects of the operation of the WIT2410.
Command
Description
zb[?|0|1]
Banner Display Disable
0 = disabled
1 = enabled (default)
zc[?|0..2]
Set Escape Sequence Mode
0 = disabled
1 = once after reset (default)
2 = unlimited times
zh?
Read factory serial number high byte.
zm?
Read factory serial number middle byte.
zl?
Read factory serial number low byte.
zp[?|0-4]
Set the duty cycle at which the modem will wake up to send and receive data.
Duty cycle equals 1/2
N
where the argument of the command equals N.
zq[?|0|1]
(remote only)
Low Power Acquisition Mode Enable
0 = Disabled (default)
1 = Enabled
z>
Exit Modem Control Mode
Banner Display Disable
Enables or disables display of the banner string and revision code automatically at power-
up. May be disabled to avoid being mistaken for data by the host.
Set Escape Sequence Mode
Enables or disables the ability to use the in-data-stream escape sequence method of
accessing Control Mode by transmitting the string ":wit2410". When this mode is set
to 1, the escape sequence only works immediately after reset (this is the default). When
set to 2, the escape sequence may be used at any time in the data stream when preceded
by a pause of 20 ms. For backwards compatibility with the WIT2400, the string
":wit2400" is also accepted for entering Control Mode. Note that the escape sequence
must be interpreted as data by the radio until the last character is received, and as such
will be generally be transmitted to a receiving radio station, if any.
Read Factory Serial Number High, Middle and Low Bytes.
These read only commands return one of the three bytes of the unique factory-set serial
number, which are also visible in the startup banner.
Set Duty Cycle
Allows reduced power consumption by having a remote wake up only every 2
N
hops to
receive and transmit. Power consumption is roughly proportional to the duty cycle
selected. For example, if N=2, the remote will wake up every fourth hop. Power
