23 | Reading this file returns a list of available protocols, | |
24 | something like: | |
25 | "rc5 [rc6] nec jvc [sony]" | |
26 | Enabled protocols are shown in [] brackets. | |
27 | Writing "+proto" will add a protocol to the list of enabled | |
28 | protocols. | |
29 | Writing "-proto" will remove a protocol from the list of enabled | |
30 | protocols. | |
31 | Writing "proto" will enable only "proto". | |
32 | Writing "none" will disable all protocols. | |
33 | Write fails with EINVAL if an invalid protocol combination or | |
34 | unknown protocol name is used. | |

41 | Sets the scancode filter expected value. | |
42 | Use in combination with /sys/class/rc/rcN/filter_mask to set the | |
43 | expected value of the bits set in the filter mask. | |
44 | If the hardware supports it then scancodes which do not match | |
45 | the filter will be ignored. Otherwise the write will fail with | |
46 | an error. | |
47 | This value may be reset to 0 if the current protocol is altered. | |

54 | Sets the scancode filter mask of bits to compare. | |
55 | Use in combination with /sys/class/rc/rcN/filter to set the bits | |
56 | of the scancode which should be compared against the expected | |
57 | value. A value of 0 disables the filter to allow all valid | |
58 | scancodes to be processed. | |
59 | If the hardware supports it then scancodes which do not match | |
60 | the filter will be ignored. Otherwise the write will fail with | |
61 | an error. | |

69 | Reading this file returns a list of available protocols to use | |
70 | for the wakeup filter, something like: | |
71 | "rc5 rc6 nec jvc [sony]" | |
72 | The enabled wakeup protocol is shown in [] brackets. | |
73 | Writing "+proto" will add a protocol to the list of enabled | |
74 | wakeup protocols. | |
75 | Writing "-proto" will remove a protocol from the list of enabled | |
76 | wakeup protocols. | |
77 | Writing "proto" will use "proto" for wakeup events. | |
78 | Writing "none" will disable wakeup. | |
79 | Write fails with EINVAL if an invalid protocol combination or | |
80 | unknown protocol name is used, or if wakeup is not supported by | |
81 | the hardware. | |
