so like. the termios functions describe a general terminal interface that's provided to control asynchronous communications ports. it's giving "I am the main character of every tty on this machine." 🔥

iykyk. the two modes have lore and that's where you find it 📖

no filtering, no buffering, just pure unhinged byte-for-byte energy. iconic honestly.

---

🌈 Line control 🌈

• tcsendbreak(3)

breaking, draining, flushing, flowing — it's a whole little ecosystem of line-management slay 💅
