Analog Status Command:
Response: <add/BCAS_'cr'
>add/BCAS_p1,p2,p3,p4'cr''lf'] Where: pn is the last parameter returned.
This command is similar to the 'BCS_' command but
returns demodulator analog parameters. Additional
status of new options and features will always be
appended to the end.
Where 'pn' = is the last parameter returned.
