Create a log file of your Motorola Surfboard SB6141 downstream signal strengths.
Uses the built-in curl to request signal strength data from your SB6141 cable modem.
HTML page 192.168.100.1/cmSignalData.htm has the signal strength numbers for the 8 downstreams.
Some HTML/DOM processing parses out the 8 values from the above page.
The eight extracted signal strengths are then logged to a file.
A small while-loop watches the clock & repeats the process every 10 seconds.
