Universal Asynchronous Receiver News Today

This post is the second in a RISC-V Bytes subseries on the PINE64 Pinecil soldering iron and development board. Previous and subsequent posts can be found under the RISC-V Bytes category. In the most recent Pinecil post, we walked through how to solder the header pins on the Pinecil breakout board. With the headers attached, we can now communicate with the Pinecil’s microcontroller via a number of protocols. Today we are going to focus on accessing the Universal Asynchronous Receiver / Tra...

Explore tty's past and present.

Being able to accurately determine your location anywhere on the planet is a useful technological trick. But when tracking isn’t done by you, but to you—without your knowledge or consent—it’s a violation of your privacy. That’s why at EFF we’ve long fought against dragnet surveillance, mobile...

The TTY demystified Real teletypes in the 1940s. The TTY subsystem is central to the design of Linux, and UNIX in general. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. I believe that a basic understanding of TTYs in Linux is essential for the developer and the advanced user. Beware, though: What you are about to see is not particularly elegant. In fact, the TTY subsystem — while quite functional from a users point of view ...
