mux_stop_tx(9)

🌸 mux_stop_tx(9) 🌸

okay so bestie, welcome to the Kernel API Manual — this one's a tiny little page from the kernel world and it's honestly giving "short but iconic" 💅

---

✨ NAME ✨

mux_stop_tx — stop transmitting characters. that's it. that's the whole job description 🎀

---

🦋 SYNOPSIS 🦋

void mux_stop_tx (struct uart_port *port );

literally just that one line, no cap ✨

---

💖 ARGUMENTS 💖

• port — a pointer to the uart_port. yep, that's the whole vibe check on this one 🫶

---

💀 DESCRIPTION 💀

so here's the tea ☕ — the Serial MUX does not support this function. like, at all. it's not a "we'll get to it" situation, it's a "this is not a thing here" situation 😭 so don't be surprised when there's nothing more to read. not me expecting a whole essay and getting one sentence 💀

bestie heads up: this function is a no-op situation — the Serial MUX doesn't support it, so don't go looking for behaviour that isn't there 🙈

okay that's the whole page, short and sweet, we ate and left no crumbs 👑✨ this little cutie lives over in ./drivers/tty/serial, dated October 2026, and yeah — that's the whole sign-off, mwah 💋🎀
