The command "setserial -b ${device}" is used to manipulate the configuration of a serial port device in Linux.
Here is the breakdown of the command:
- "setserial" is the main command used to interact with and configure serial ports. It is responsible for querying or modifying the settings of a serial port.
- "-b" is an option or flag that stands for "baud base" and is used to specify that the following baud rate should be treated as a base for calculations.
- "${device}" is a placeholder variable that should be replaced with the actual name of the serial port device. For example, "/dev/ttyS0" represents the first serial port, and "/dev/ttyUSB0" represents a USB serial port.
In summary, the command "setserial -b ${device}" is used to modify the baud rate settings for a specific serial port device in Linux.
