tty_port_lower_dtr_rts(9)

✨ NAME ✨

okay bestie, welcome to the tty_port_lower_dtr_rts(9) page in the Kernel API Manual 💖 this one is literally about tty_port_lower_dtr_rts — Lower DTR/RTS ✨

📜 SYNOPSIS 📜

void tty_port_lower_dtr_rts (struct tty_port *port );

🎀 ARGUMENTS 🎀

• port — tty port 🫶

💅 DESCRIPTION 💅

So this is a wrapper for the DTR/RTS raise logic, no cap. For the moment, it’s used to hide some internal details 👀. This will eventually become entirely internal to the tty port — like, that’s the plan, bestie ✨
