19 direwolf is a software "soundcard" modem/TNC and APRS encoder/decoder.
20 It can be used stand-alone to receive APRS messages, as a digipeater,
21 APRStt gateway, or Internet Gateway (IGate). It can also be used as a
22 virtual TNC for other applications such as APRSIS32, UI-View32, Xastir,
23 APRS-TW, YAAC, UISS, Linux AX25, SARTrack, RMS Express, and many oth‐
24 ers.

30 Read configuration file from specified location rather than the
31 default locations.

34 -l logdir
35 Generate daily log files in specified directory. Use "." for
36 current directory.

42
43 -r n Audio sample rate per second for first channel. Default 44100.
44
45
46 -n n Number of audio channels for first device. 1 or 2. Default 1.
47
48
49 -b n Audio sample size for first channel. 8 or 16. Default 16.
50
51
52 -B n Data rate in bits/sec for first channel. Standard values are
53 300, 1200, 9600.
54 If < 600, tones are set to 1600 & 1800.
55 If > 2400, K9NG/G3RUH scrambling is used.
56 Otherwise, AFSK tones are set to 1200 & 2200.
57
58
59 -D n Divide audio sample by n for first channel.
60
61
62 -d x Debug options. Specify one or more of the following in place of
63 x.
64 a = AGWPE network protocol client.
65 k = KISS serial port client.
66 n = Network KISS client.
67 u = Display non-ASCII text in hexadecimal.
68 p = Packet dump in hexadecimal.
69 g = GPS interface.
70 W = Waypoints for position or object reports.
71 t = Tracker beacon.
72 o = Output controls such as PTT and DCD.
73 i = IGate
74 h = Hamlib verbose level. Repeat for more.
75
76
77 -q x Quiet (suppress output). Specify one or more of the following in
78 place of x.
79 h = Heard line with the audio level.
80 d = Decoding of APRS packets.
81
82
83 -t n Text colors. 1=normal, 0=disabled.
84
85
86 -p Enable pseudo terminal for KISS protocol.
87
88
89 -x Send Xmit level calibration tones.
90
91
92 -U Print UTF-8 test string and exit.
93
94
95 -S Print Symbol tables and exit.
96
97
98 -a n Report audio device statistics each n seconds.

103 gqrx (2.3 and later) has the ability to send streaming audio through a
104 UDP socket to another application for further processing. direwolf can
105 listen over a UDP port with options like this:
106
107 direwolf -n 1 -r 48000 -b 16 udp:7355
108
109 Other SDR applications might produce audio on stdout so it is conve‐
110 nient to pipe into the next application. In this example, the final
111 "-" means read from stdin.
