discover() sets lowball mode to the mode requested (length too), and begins to dump packets to the screen.
press <enter> to quit, and your radio config will be set back to its original configuration.
lowball - lowball level of choosing (see help on lowball)
debug - sets _debug to this setting if not None.
length - arbitrary length of bytes we want to see per pseudopacket. (should be enough to identify interesting packets, but not too long)
IdentSyncWord - look for preamble in each packet and determine possible sync-words in use
SyncWordMatchList - attempt to find *these* sync words (provide a list)
Search - byte string to search through each received packet for (real bytes, not hex repr)
RegExpSearch - regular expression to search through received bytes (not the hex repr that is printed)
if IdentSyncWord == True (or SyncWordMatchList != None), returns a dict of unique possible SyncWords identified along with the number of times seen.
