Final answer:
To connect to a target via a serial port, one must use terminal emulation software to select the COM port and set communication parameters, with common Unix commands being 'screen' and 'minicom' for such connections.
Step-by-step explanation:
To connect to a target using a serial port connection, you primarily use terminal emulation software that allows serial communication. Commonly used commands or actions involve selecting the appropriate COM port and configuring settings such as baud rate, data bits, stop bits, and parity. Examples of terminal emulation software include PuTTY, Tera Term, and HyperTerminal. In a Unix-like system, the 'screen' or 'minicom' command can be used to connect to the serial device.
For example, in Unix/Linux, to connect to a serial device using screen, you would use:
screen /dev/ttyS0 115200
This command connects you to the device at /dev/ttyS0 using a baud rate of 115200. Similarly, minicom setup configuration can be accessed with: minicom -s Once in the setup menu, you can configure the various connection parameters to match the target device's requirements.
