235 | <para>Some receivers are equipped with special wide band receiver which is intended | ||
236 | to be used to learn output of existing remote. | ||
237 | Calling that ioctl with (1) will enable it, and with (0) disable it. | ||
238 | This might be useful of receivers that have otherwise narrow band receiver | ||
239 | that prevents them to be used with some remotes. | ||
240 | Wide band receiver might also be more precise | ||
241 | On the other hand its disadvantage it usually reduced range of reception. | ||
242 | Note: wide band receiver might be implictly enabled if you enable | ||
243 | carrier reports. In that case it will be disabled as soon as you disable | ||
244 | carrier reports. Trying to disable wide band receiver while carrier | ||
245 | reports are active will do nothing.</para> | ||
