✨ NAME ✨

uark — Arkmicro Technologies ARK3116 based USB serial adapter 🦋

🌸 SYNOPSIS 🌸

so like, if you wanna bake this driver into the kernel (main character energy, no cap), you drop these lines into your kernel configuration file:

device usb
device ucom
device uark

orrr, if you'd rather load it as a module at boot time like a chill low-key legend, put this line in loader.conf(5):

uark_load="YES"

both are valid, both are iconic, pick your fighter 💅

⭐ HISTORY ⭐

The uark device driver first appeared in OpenBSD 4.0. The first FreeBSD release to include it was FreeBSD 7.0. a whole era. a glow-up. we love to see it 👑

💜 AUTHORS 💜

The uark driver was written by Jonathan Gray <jsg@openbsd.org>. thank you for your service king 🫡✨

😭 CAVEATS 😭

okay so this is the part where we get real, and it's a little sad:

  • Setting hardware flow control is not currently supported. no cap, it's just not there yet.
  • It is not yet known how to ask the hardware to send a break. we simply do not know. it's a mystery 🕵️
Arkmicro Technologies do not reply to requests of documentation for their products. 💀 so like, we're on our own here bestie, we figured it out ourselves and that's actually kind of iconic of us.

Debian 🌸 April 26, 2017 🌸 that's the source, the version and the date, mwah 💋 this has been UARK(4), go forth and serialize, ily, bye 🦋💖✨
