💜 HISTORY 💜

The uvisor driver was adopted from NetBSD 1.5 in August 2002. This manual page was adopted from NetBSD by Tom Rhodes <trhodes@FreeBSD.org> at that time. Vintage-code lore, honestly iconic. 🕰️

💀 BUGS 💀

🚨 The code to provide multiple ucom(4) instances has not yet been ported from NetBSD. It is unclear whether this driver works in its current state.

Not me ending on a “we don’t totally know if this works” note 😭 — but that’s literally what the page says, so keep that energy in mind. 🙈

okay that’s the whole page, mwah 💋 — source/version: Debian, date: April 26, 2017. Periodt. 🎀✨
