sudo is a command that allows the user to run another command with superuser privileges.
minicom is a terminal emulation program that allows the user to communicate with a serial device. The --device flag followed by /dev/ttyUSB0 specifies the serial device that minicom should use for communication. The --baudrate flag followed by 9600 specifies the baud rate (i.e. the speed at which data is transmitted) of the serial connection. The --8bit flag sets the number of data bits to 8.
So this command is running minicom as a superuser, connecting to the device at “/dev/ttyUSB0” with a baud rate of 9600 and 8-bit data
In addition to the command line arguments above, we had to ensure that flow control (both hardware and software) was off and no parity was given.
Today, we found in stock some USB thermometers by papouch, which we decided to put to use. We wanted to create a small bash script that would take the measurements from the thermometers and log them along with the system date/time. After doing some minor research we got to the…
Background Recently we started using the UC232A USB-to-Serial Converter to connect to a board. The software we used was TeraTerm on a 64bit Windows 10 without installing custom drivers. Our serial port configuration was the following: Baud rate: 115200 Data: 8 bit Parity: none Stop: 1 bit Flow control: none…
A very important tool in our everyday life are the LiveUSB GNU/Linux flash drives. We keep an updated collection of several GNU/Linux flavors/distributions (Fedora, CentOS, (L/X)Ubuntu, Kali etc.) that are used depending on the scenario. The command we use is the following: dd allows you to convert and copy a file…
