GRIP (?) {x}
The GRIP x command sets the GRI to the value x, where x is in units of
micro seconds and may range from 40000 to 99990 micro seconds.
The value is rounded to the nearest 10 ms. The GRIP? query returns
the current GRI setting in units of micro seconds. NOTE: If this
command is sent while the FS700 is locked to a station, the command
will be ignored and an execution error generated. The FS700 must first
be made to stop tracking using the STOP command.
STOP
The STOP command causes the FS700 to stop tracking a station.
NOTE: If the search mode is set to AUTO, acquisition will
automatically restart. To manually control the acquisition process, the
search mode should be set to manual.
STRT
The STRT command causes the FS700 to begin station acquisition. If
the FS700 is already tracking a station, this command will cause
tracking to be restarted.
STTN (?) {i}
The STTN i command sets the station to be searched for to i. The
correspondence of i values to the LORAN stations is shown in the table
below. Because the secondary stations in different chains transmit in
different orders, look in the station list to determine which secondary
station index (1,2,3,4,5) corresponds to which station (V,W,X,Y,Z). If i
= -1 the FS700 is set to auto station selection and will lock to the largest
station. The STTN ? query will return the index of the station to which
the FS700 is supposed to lock. If the FS700 is set to auto station
selection, the STTN? query will return the value -1. The actual station
that the FS700 picked may be determined using the LSTA? query.
NOTE: If this command is sent while the FS700 is locked to a station,
the command will be ignored and an execution error generated. The
FS700 must first be made to stop tracking using the STOP command.

GAIN?
The GAIN? query returns the receiver gain (in dB between 0 and 120)
during the time that the station being locked to is transmitting. If a
station has not been selected -999 will be returned.
INFO? i
The INFO? i query returns the amplitude and identification information
about the i'th station that was located in the station search. The
