PuTTY is a Windows and Linux tool used to connect Serial and SSH services. As a Serial line tool, it provides different options for the connection. The serial connection provides configuration like baud rate, number of data bits, stop bits, parity flow control, etc. By default, the pressed key is sent to the serial line without printing it into the PuTTY terminal.
