DESCRIPTION

25       dpauxmon is an extcap tool that can capture DisplayPort AUX channel
26       data from linux kernel drivers using the generic netlink interface.
27
28       Supported interfaces:
29
30        1. dpauxmon
31

EXAMPLES

71       To see program arguments:
72
73           dpauxmon --help
74
75       To see program version:
76
77           dpauxmon --version
78
79       To see interfaces:
80
81           dpauxmon --extcap-interfaces
82
83       Only one interface (dpauxmon) is supported.
84
85       Example output
86
87           interface {value=dpauxmon}{display=DisplayPort AUX channel capture}
88
89       To see interface DLTs:
90
91           dpauxmon --extcap-interface=dpauxmon --extcap-dlts
92
93       Example output
94
95           dlt {number=275}{name=dpauxmon}{display=DisplayPort AUX channel monitor DLT}
96
97       To see interface configuration options:
98
99           dpauxmon --extcap-interface=dpauxmon --extcap-config
100
101       Example output
102
103           dpauxmon --extcap-interface=dpauxmon --extcap-config
104           arg {number=0}{call=--interface_id}{display=Interface Id}
105               {type=unsigned}{tooltip=The Interface Id}
106               {required=true}
107
108       To capture:
109
110           dpauxmon --extcap-interface=dpauxmon --fifo=/tmp/dpauxmon.pcap --capture --interface_id 0
