Available commands (from USB interface using a terminal emulator:
-----------------------------------------------------------------
?   This help text
L   Display the copyright and license terms.
M   Display/set the minimum frequency.
H   Display/set the highest frequency.
I   Display/set the IF frequency value.
C   Display/set the frequency correction factor in ppm.
S   Display/set the frequency at which OL switches
    from above to under RX frequency.
B   Display/set the band change detection threshold.
W   Save configuration parameters in EEPROM.
T   Perform a display test.
-----------------------------------------------------------------
The only parameter which is mandatory to set is the frequency
correction factor (by default, 0); all others parameters are
automatically set to a value suitable for a BC312/BC342, i.e.
    - minimum frequency (M) 1500kHz.
    - highest frequency (H) 18000kHz.
    - IF frequency (I) 470kHz.
    - OL above/under switching frequency (S) 8000kHz.
    - band change detection threshold 1000kHz.

The command syntax is
        <command> <value><CR>
e.g.
        C -600<CR>
sets a -600ppm frequency correction factor.

Commands can be issued either upper or lower case.

If a command that requires a parameter is issued without one,
the current value of that parameter is displayed.

Frequency values must be expressed in 100Hz units; e.g. to set
an IF frequency of 470kHz, issue the command
        I 4700<CR>
