0=Offline
1=Online
Example: RED=1 (which is Online)
Query only.
Unit returns the value of the internal temperature sensor, in the

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, or.
abcdef which is the FLT? response information from
the offline 600/L unit.
abcdefghxx which is the FLT? response information from the
offline 625 unit.
