The BNU serial port driver was specifically targeted for use with early (late 1980s - 1990s) DOS-based BBS software. The reason for BNU and other similar enhanced serial port drivers was to provide better support for serial communications software than what was offered by the machine's BIOS and/or DOS being used on the machine.
Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent from a data communications equipment (DCE) to a data terminal equipment (DTE), i.e., from the modem ...
SIO is a serial port driver package for OS/2 written by Raymond L. Gwinn. It is designed to not only improve performance over OS/2's default serial drivers, but also improve compatibility. SIO contains a virtualized FOSSIL (VX00) driver that can be loaded to provide FOSSIL support to DOS based communications software.
A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232 , RS-485 , RS-422 , or TTL-level UART serial data.
Using another lower-level device driver (e.g. file system drivers using disk drivers) Simulating work with hardware, while doing something entirely different [9] For software: Allowing the operating system direct access to hardware resources; Implementing only primitives; Implementing an interface for non-driver software (e.g. TWAIN)
Many RS-232 driver chips have inbuilt charge pump circuitry to produce the required voltages from a 3 or 5 volt supply. RS-232 drivers and receivers must be able to withstand indefinite short circuits to the ground or to any voltage level up to ±25 volts. The slew rate, or how fast the signal changes between levels, is also controlled.

Serial port (COM port) - At one time the most popular method. Serial ports usually lack adequate circuit programming supply voltage. Most computers and laptops newer than 2010 lack support for this port. Socket (in or out of circuit) - the CPU must be either removed from circuit board, or a clamp must be attached to the chip-making access an issue.
