💀 CAVEATS 💀

Setting hardware flow control is not currently supported 😭. It is not yet known how to ask the hardware to send a break. Also, Arkmicro Technologies do not reply to requests of documentation for their products — not the vibe, fr fr.

This little manual page is from the Debian edition, dated April 26, 2017, and yes bestie, it’s the UARK(4) page 💅✨🎀
