# Extract new Radio and Talkgroup IDs from Control Channel data dumps made 
# via a Radio Shack PRO-651/PRO-652 (or GRE equiv.) scanner.
#
# It's a total hack, but seems to work...
#
# Create the logs under Linux using 'minicom' and a Radio Shack USB scanner 
# programming cable (Cat. No. 20-546).
#
# Usage: ./extractIDs.sh 'filename'
#
# Where 'filename' is the capture file of the Control Channel data made
# using minicom.
#
# To enable text capture under minicom, use 'CTRL-A' then 'L'.
# Enter the name of the file you want to save the data in.
# Use 'CTRL-A' then 'L' again to stop or pause the capture of data.
