XPP_BLINK(8)

✨ XPP_BLINK ✨

okay bestie, so this is the xpp_blink page from section 8 of the manual — the one about blinking the leds of a specified XPD. yes, leds. yes, blinking. we love a low-stakes king. 💅

🌸 NAME 🌸

xpp_blink — Blink the leds of a specified XPD

---

🎀 SYNOPSIS 🎀

xpp_blink {on|off|bzzt} {span <number> | chan <number> | xpd <bus num>
[<xpd num> [<lineno>]]}

ok so quick vibe check: you gotta say what you want the leds to do, and which XPD you mean. two decisions. you got this. 🌈

---

💖 DESCRIPTION 💖

Blink all the leds of an XPD. that's it. that's the whole job. and honestly? iconic. the way it just... blinks. 👑

✨ Blink mode: ✨

this is the first lil word you hand it. pick one, no cap:

• on — Turn on constant blink. (yes, "constant blink" is the energy we're going for. it blinks. constantly. forever. main character.)
• off — Turn off blink. the leds go back to being mysterious and silent. 💀
• bzzt — Blink briefly for 1 second. a lil sparkle, a lil ✨bzzt✨, and then it's over. fleeting. beautiful. gone.

🦋 Selector: 🦋

and this is the second word, aka which one:

• span — Select by span number. This only work for XPD registered to dahdi. it will also print the dahdi channels of the span and the xbus/xpd this span represents. free info, we love a bonus. 🫶
• chan — Select by channel number. This only work for XPD registered to dahdi.
• xpd — Select by xbus + xpd numbers. And hey, plot twist: if only the xbus number is given, all the XPDs of the selected xbus (Astribank) are blinked. group blink. party vibe. 🔥
• label — Select by xbus label. Affect the whole Astribank. one label, everybody blinks, periodt.

🌟 EXAMPLES 🌟

give the people what they want — real ones, verbatim:

$ xpp_blink bzzt span 2
Using XBUS-04/XPD-10 (connected via usb-0000:00:1d.7-1): channels 15 16 17 18 19 20 21 22

$ xpp_blink bzzt chan 18

$ xpp_blink on xpd 0 1 5

$ xpp_blink off xpd 0

$ xpp_blink bzzt label 'usb:00000238'

look at example one just spilling the tea — Using XBUS-04/XPD-10 (connected via usb-0000:00:1d.7-1): channels 15 16 17 18 19 20 21 22. that's the span selector doing its little bonus-print thing. ate. 🍓

and notice xpd 0 on its own = all the XPDs of xbus 0 get the blink treatment. no xpd num needed. iykyk. 😭

friendly reminder bestie: the span and chan selectors only work for XPD registered to dahdi. don't come for them if they ghost you outside dahdi. 🙈
