+What: /sys/class/rc/rcN/protocols
+Date: Jun 2010
+KernelVersion: 2.6.36
+Contact: Mauro Carvalho Chehab <m.chehab@samsung.com>
+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.
