lowkey a reminder bestie: this page is just the getter. it gets the modem control state, it doesn't set it, it doesn't configure anything, it just gets. don't be out here expecting more from it, ok? 🙈

and that's the page!! 🌸 source/version-wise we're hanging out in ./drivers/tty/serial, dated October 2026 — so yeah, mark your calendar, screenshot it, whatever, mwah 💋✨ go get that modem control state bestie, you're gonna slay 🫶🔥
