Explanation

Serial communication settings are expressed as data bits, parity, and stop bits. The industry standard default for most external modems is 8N1: 8 data bits, No parity, and 1 stop bit. This is the most widely supported configuration and is the default for virtually all modern serial modems. Option C (8, None, 1) matches this standard exactly. Options with 6 data bits or parity enabled are non-standard for modems.
