- -e
- (fix extended frame format output - no auto detect)
- -b
- (start with binary mode)
- -8
- (start with binary mode - for EFF on 80 chars)
- -B
- (start with binary mode with gap - exceeds 80 chars!)
- -c
- (color changes)
- -t <time>
- (timeout for ID display [x10ms] default: 500, 0 = OFF)
- -h <time>
- (hold marker on changes [x10ms] default: 100)
- -l <time>
- (loop time (display) [x10ms] default: 20)

- (print this help text)
Use interface name 'any' to receive from all can-interfaces.
commands that can be entered at runtime:¶
- q<ENTER>

- b<ENTER>
- - toggle binary / HEX-ASCII output
- 8<ENTER>
- - toggle binary / HEX-ASCII output (small for EFF on 80 chars)
- B<ENTER>
- - toggle binary with gap / HEX-ASCII output (exceeds 80 chars!)
- c<ENTER>

- <SPACE><ENTER>
- - force a clear screen
- #<ENTER>

- rMYNAME<ENTER>

- wMYNAME<ENTER>
- - write settings file (filter/notch)
- a<ENTER>
- - enable 'a'll SFF CAN-IDs to sniff
- n<ENTER>
- - enable 'n'one SFF CAN-IDs to sniff
- A<ENTER>
- - enable 'A'll EFF CAN-IDs to sniff
- N<ENTER>
- - enable 'N'one EFF CAN-IDs to sniff
+FILTER<ENTER> - add CAN-IDs to sniff
-FILTER<ENTER> - remove CAN-IDs to sniff
FILTER can be a single CAN-ID or a CAN-ID/Bitmask:
- single SFF 11 bit IDs:
+1F5<ENTER> - add SFF CAN-ID 0x1F5
-42E<ENTER> - remove SFF CAN-ID 0x42E
- single EFF 29 bit IDs:
+18FEDF55<ENTER> - add EFF CAN-ID 0x18FEDF55
-00000090<ENTER> - remove EFF CAN-ID 0x00000090
- CAN-ID/Bitmask SFF:
-42E7FF<ENTER> - remove SFF CAN-ID 0x42E (using Bitmask)
-500700<ENTER> - remove SFF CAN-IDs 0x500 - 0x5FF
+400600<ENTER> - add SFF CAN-IDs 0x400 - 0x5FF
+000000<ENTER> - add all SFF CAN-IDs
-000000<ENTER> - remove all SFF CAN-IDs
- CAN-ID/Bitmask EFF:
-0000000000000000<ENTER> - remove all EFF CAN-IDs
+12345678000000FF<ENTER> - add EFF CAN IDs xxxxxx78
+0000000000000000<ENTER> - add all EFF CAN-IDs
if (id & filter) == (sniff-id & filter) the action (+/-) is performed, which is quite easy when the filter is 000 resp. 00000000 for EFF.
