Response to ASCII codes between 48 and 57)
Query
1 byte, Forces the unit to store the current modem configuration in
numerical, 0 to 9 Configuration Memory location defined by the one byte
argument (0 to 9).
Example CST=4 (Store current config in location 4)
WARNING: Use with caution! If the location already contains
data it will be automatically overwritten. If in doubt, query the
location first.
1 byte, Command only.
numerical, 0 to 9 Forces the unit to retrieve the Configuration Memory location
defined by the one byte argument (0 to 9). and to re-program
the unit with that stored configuration.
None Command only.
Forces the unit to re-center the receive plesiochronous/doppler
buffer.
This command takes no arguments.
None Command only.
Forces the unit to toggle the Unit Fail relay to the 'fail' state
for approx 500ms. If the unit is a 1:1 pair, and it is currently
the 'On Line' unit, this will force a switchover, so the unit will
then be in 'Standby' mode. The command is always executed
by the unit, regardless of whether it is stand-alone, in a 1:1
pair, or part of a 1:N system.
This command takes no arguments.
1 byte, value of FACTORY USE ONLY
0 or 1 Modulator output 10dB attenuator setting, where
0 = no attenuation
1 = 10 dB attenuation
Example: ATS=0
