Description of Arguments
Query only. (1:1 set-up)
This query is sent to the online modem of a 1:1 pair. It
provides access to the fault status information (FLT?) of
the offline modem. This is the only way to interrogate the
status of an offline modem at the distant-end of a link.
The response format may be:
No1for1 which indicates that no 1:1 system has been
detected. Presence of a 1kHz signal from the CRS-150
is used to indicate a 1:1 set-up.
NoComm which indicates that a 1kHz signal has been
detected, but that there is no (or not yet) a response for
the modem.
abcdef would be the FLT? response information from
the offline unit.
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.
