gsm_encode_modem(9)

💅 gsm_encode_modem ✨

okay so bestie, this is a page from the Kernel API Manual and it's literally about turning modem status into bits 🎀 stay with me, it's shorter than it looks, i promise

---

🌸 NAME 🌸

gsm_encode_modem — encode modem data bits 💫

---

✨ SYNOPSIS ✨

u8 gsm_encode_modem (const struct gsm_dlci *dlci );

yes the return type is u8, yes there's a tiny space before the closing paren, no we don't fix it, we respect the source 💅

---

🎀 ARGUMENTS 🎀

• dlci — the DLCI you're encoding from, bestie. that's the one. 🦋

---

💖 DESCRIPTION 💖

So what does it actually do? It returns the correct GSM encoded modem status bits — and heads up, that's a 6 bit field, not the whole byte, okay? — for the current status of the DLCI and the tty object attached to it. 🫶

That's it. That's the whole function. Short king. 👑

bye bestie, go encode some modem bits, you're gonna slay 🦋💖
