uartdrive

uartdrive is a small Linux program written in C that opens and configures a UART (universal asynchronous receiver-transmitter) interface. A UART is the kind of low-speed serial link commonly found between a computer and small hardware devices like microcontrollers, sensors, GPS modules, or single-board computers. On Linux, these connections show up as character device files such as /dev/ttyUSB0 or /dev/ttyS0.

The README is short. Installation is straightforward: clone the repository, run the included build.sh script after marking it executable, and a single binary called uartdrive is produced inside the project folder.

Once built, the program takes one argument, the path to a tty device file. Running it with a valid path tells the program to find and open that tty, then configure it as a UART connection. The configuration is done through the termios API, which is the standard Linux interface for controlling terminal and serial port settings such as baud rate, parity, stop bits, and flow control.

Once the link is set up, the program sends a test message over the line. It also listens for incoming bytes on the same connection and prints any received data to standard output in a formatted way. So in practice, it acts as a minimal handshake-and-monitor tool: open the port, say hello, and show whatever comes back.

The README does not mention which baud rate, framing, or flow control settings the program picks, what the test message contains, what the output format looks like, or which Linux kernels and distributions have been tested. There is no licence section. The author closes by inviting readers to point out inconsistencies in the code and to send patches, which is the only contribution guidance offered.
