[arm-allstar] simpleusb realtime RX telemetry

[David McGough]

Hi Guys,

Well, yes, via hackery telemetry results can be obtained.

THIS IS NOT RECOMMENDED! That internal interface was designed for 
simpleusb-tune-menu, not other applications, and may change at any time! I 
can almost guarantee it will change!

The better solution is to get results from the Asterisk Manager interface, 
similar to the mechanisms used by AllMon and Supermon.

As the old sports car adage goes: Your mileage will vary between the
required tune-ups!

Use "expect" after installing it via "pacman -S expect". Then build the 
script:

autoexpect /usr/bin/simpleusb-tune-menu

and after entering the desired inputs "V" etc., run the resultant script 
from the command line or via cron, and parse its output to get what you 
want, e.g.:

# ./script.exp | grep -A3 "^REAL"
REALTIME RX TELEMETRY DISPLAY:
 Â Â Â  COSÂ Â Â Â  |Â Â  COSÂ Â  |Â  COSÂ Â  |Â  CTCSSÂ  |Â Â  CTCSSÂ Â Â  | PTT
(composite) | (input) | (test) | (input) | (override) |
 Â Â  CLEARÂ Â Â  |Â  CLEARÂ  | CLEARÂ  | IGNOREÂ  |Â Â  CLEARÂ Â Â  | CLEAR

The man pages for expect and autoexpect are of course more informative, 
but this simple example should pique your interest as it meets your request.
