For normal verbs, just pass numbers. You can pass numbers to PARAMETERSverb, too, of course. Also, the verb itself can be a number. > I've found the widget below in HP DV6 (OUT HP Detect grabbed my> attention and I've seen that the unsolicited events has something to do> with HP sense/automute, just playling blindly),> > Node 0x0a [Pin Complex] wcaps 0x400181: Stereo> Pincap 0x0000001c: OUT HP Detect **> Pin Default 0x40f100f0: [N/A] Other at Ext N/A> Conn = 1/8, Color = Unknown> DefAssociation = 0xf, Sequence = 0x0> Pin-ctls: 0x00:> Unsolicited: tag=0c, enabled=0> Connection: 3> 0x10 0x11 0x17*> > and say that I want to send SET_UNSOLICITED_ENABLE to 0x0a, which PARM> should I choose? For SET_UNSOLICITED_ENABLE verb, you need to a value (TAG | AC_USRSP_EN).in the case of above, suppose the tag to be 0x0c, pass 0x8c.
