See: + * http://www.x10.com/products/lola_sg1.htm + * The Lola is similar to the ATI remote but has no mouse support, and slightly + * different keys. + * + * It is possible to use multiple receivers and remotes on multiple computers + * simultaneously by configuring them to use specific channels. + * + * The RF protocol used by the remote supports 16 distinct channels, 1 to 16. + * Actually, it may even support more, at least in some revisions of the + * hardware. + * + * Each remote can be configured to transmit on one channel as follows: + * - Press and hold the "hand icon" button. + * - When the red LED starts to blink, let go of the "hand icon" button. + * - When it stops blinking, input the channel code as two digits, from 01 + * to 16, and press the hand icon again. + * + * The timing can be a little tricky. Try loading the module with debug=1 + * to have the kernel print out messages about the remote control number + * and mask. Note: debugging prints remote numbers as zero-based hexadecimal. + * + * The driver has a "channel_mask" parameter. This bitmask specifies which + * channels will be ignored by the module. To mask out channels, just add + * all the 2^channel_number values together. + * + * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote + * ignore signals coming from remote controls transmitting on channel 4, but + * accept all other channels. + * + * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be + * ignored. + * + * The default is 0 (respond to all channels).

If it counts more than 7 clicks before it is polled, it will wrap back - * to zero and start counting again. This was at quite high speed, however, almost - * certainly faster than the human hand could turn it.
