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.
