 -a <paths>     user message ack path eg. WIDE2-2 or - for no path
 -b <s>:<file>  enable beacon every s(econds) path and text from <file>
                cycles thru lines in file, empty lines = no tx (size max 32kb)

                file may be modified any time eg. by telemetry program
 -c <ip>:<port> send text monitor udp frame with cr lf
 -D             output decoded Data to stdout
 -d <call>      digipeater enable (and dupe filter) call
 -d -           dupe filter without data modification
 -e             echo last (filtert) output
 -f <filterparm>  'p<x>,<x>...' pass UI frames with first char (-f p58,110)
                  'd<x>,<x>...' pass UI frames with not first char (-f d32,65-79)
                  Messages to itself are treated as Telemetry  (-f d84)

 -k <deg>/<deg>/<km> distance filter, center/radius -k 48.2/13.5/100
                -k 0/0/20000 remove all (not user msg) with no position data
 -L <ip>:<port>:<netname>   read monitor rflink header with netname
 -l <ip>:<port> send raw axudp frame and pass thru axudp2 header
 -M <ip>:<port> read text monitor udp frame
                ip=255.255.255.255:0 read text monitor from stdin
                ip=255.255.255.255:1 read text monitor from stdin and terminate

 -p <n>,<...>   -p 7,8 igate friendly digi relaying all direct heared
                -p 5,6,7,8,9 first hop digi, -p 3,4 (noisy) last hop digi
                -p 0,1,3,4,5,6,7,8,9,14,16 original, noisy, path loosing ...
                0..2 limit ssid-routing to (bit0 + 2*bit1 + 4*bit2)
                dest-3: dest-2,digicall*, dest-3,call*: dest-2,call,digicall*
                3 allow repeatet before (mostly with wrong path trace)
                4 no uplink check for 'looks like direct heared'
                  (noisy, wrong path trace possible)
                5 resend TRACEn-(N-1), 6 resend WIDEn-(N-1)
                  so frames may be relayed again by loss of downlink trace
                7 append remaining digi path after via digicall
                8 append remaining digi path after RELAY/GATE/TRACE
                9 append remaining digi path after WIDE
                  so frames may be relayed again by loss of downlink trace
                10, 11, 12, 13 switch off via digicall, RELAY, TRACE, WIDE
                14 insert not digicall on direct heared before WIDEn-N,
                   as others do, your digi is hidden, and path is shown wrong
                15 convert destination ssid routing to WIDEn-n
                16 send n-0 without repeated flag
                17 remove all WIDE from downlink path
                18 enable via GATE (use as gate: disable via all other)
                19 allow ECHO as alias to RELAY
 -P <s>         piggyback time sending beacon earlier if sent anything now
 -R <ip>:<port> read raw axudp frame, 0 ip read from all (-R 0.0.0.0:2000)
 -r <ip>:<port> send raw axudp frame
 -S             Satgate, filter out uplink (has via with no h-bit)
 -s             pass not-UI-frames too (all PR-Frames, SABM, RR..)
                (raw axudp only) and axudp2 modem to layer2 message frames
 -t <s>,<s>     dupe filter time in seconds (all types, user messages)
                -t 1740,28 29min not same beacon, 28s for retrying user message)
 -u <call>:<file> global option, receive & ack usermessages to call store in file
                repeat -u for more Calls to same or different File
 -v             show frames and analytics on stdout
 -X             same as -x but pass only frames with this calls
 -x <call>{,<call>} delete frames with call in a address field, -x TCPIP,N?CALL*
