The term "COM" itself is a legacy designation from MS-DOS and early Windows systems, where each physical or virtual port was assigned a label such as COM1 or COM2 to manage the hardware resources efficiently. 5, or 2 bits to signal a pause before the next character.

Data Bits: Typically set to 8 (for standard ASCII or UTF-8), this specifies the number of data bits sent per character. These virtual interfaces appear exactly like physical COM ports to the operating system, allowing legacy software to communicate with USB-connected devices such as microcontrollers, GPS modules, or industrial sensors without modification.
Understanding the Fundamentals of Serial Communication At its core, a com serial port operates by sending data one bit at a time over a single wire pair, contrasting with parallel communication which sends multiple bits simultaneously. In modern Windows, Linux, and macOS environments, the com serial port can be emulated through software, creating a virtual com port (VCP).

These settings, often adjusted in a terminal emulator or device driver configuration, dictate how the bits are interpreted. Standard rates include 9600, 19200, and 115200, and both devices must use the exact same rate.
