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