| 22 | Description: |
| 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. |

| 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 |
