mux_stop_rx(9)

💅 mux_stop_rx — a Kernel API Manual moment

okay so welcome to mux_stop_rx(9), bestie 💖 this one's a tiny little page from the Kernel API Manual and honestly? it's giving "short but iconic." let's get into it ✨

---

✨ NAME ✨

mux_stop_rx — Stop receiving characters.

Like, literally that's the whole pitch 🎀

---

🌸 SYNOPSIS 🌸

void mux_stop_rx (struct uart_port *port );

that's it. that's the function. no cap 💅

---

🦋 ARGUMENTS 🦋

• port — Ptr to the uart_port. yes, the actual struct uart_port bestie, not a vibe, not a metaphor, an actual pointer to one 🫶

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ and it's a lil bit of a letdown ngl — the Serial Mux does not support this function.

that's it. that's the whole description. no hidden lore, no secret behaviour, no "well actually if you…" — the Serial Mux straight up does not support it 🙈 so don't go expecting it to stop receiving characters for you, because it won't. main character energy: unfulfilled 😭
