💖 wwan_port_txon(9) 💖

okay so bestie, welcome to the Kernel API Manual page for wwan_port_txon(9) — yes that's the header, yes it's giving very "I live in man 9 and I'm thriving" ✨

🌸 NAME 🌸

wwan_port_txon — Restart TX on WWAN port 🫶

like, the actual name of the thing. TX is back, babes.

---

🦋 SYNOPSIS 🦋

void wwan_port_txon (struct wwan_port *port );

that's the whole signature, no cap. it returns void, so like… nothing comes back. it just does the thing 💅

---

🎀 ARGUMENTS 🎀

• port — the WWAN port for which TX must be restarted. literally the one port that needs its TX restarted, that's it, that's the whole argument 🧚

---

✨ DESCRIPTION ✨

okay so this is a TX flow control situation, and it's lowkey iconic. a port driver calls this function to say "TX is available again" — that's it. that's the entire job. TX was off, now TX is on, the vibes are restored 🔥

no extra steps, no secret sauce, just the port driver hitting this function to signal availability. main character energy tbh 👑
