Understanding Broadband over Power Lines
Published in Gilbert Held, Understanding Broadband over Power Line, 2016
The low data rate reflected limits on the serial port of computers during the 1970s and 1980s, which limited the transfer rate to, at best, 19,200 bps during the 1970s and 115,000 bps during the 1980s, with the higher transfer rate resulting from the introduction of buffered universal asynchronous receiver-transmitters (UARTs).

The Arduino board uses a port to communicate with a PC through serial communication and Unity interfacing. Serial communication is the process of sending/receiving data one bit at a time, and a serial port is an interface that allows a PC to transmit or receive data one bit at a time.

In the past, printers were interconnected by specific and bulky parallel ports. External devices such as ZIP drives would require a high-speed connection to the computer using the parallel port, but personal computers would usually have low speed. Serial ports provided another typical connection in old computers. Modems used the serial port, just as many printers and a variety of devices such as laptops, Palm Pilots, and digital cameras. Most computers have at most two serial ports and are often very slow. Devices that earlier needed faster connections came with their cards, which fit into expansion slots inside the computer case. Unfortunately, the number of expansion slots is limited, and, in some cases, a skilled technician is required to install the software. The goal of USB is to end these difficulties. The USB provides a single, standardized, and easy way to connect up to 127 devices on a computer. Currently, almost all peripherals are available in a version for USB. Examples of USB devices that can be purchased nowadays include the following:PrintersScannersMousePen driveJoysticksConsoles for flight simulatorsDigital camerasWebcamDevices for the acquisition of scientific dataModemsSpeakersPhonesVideo phonesData storage devicesNetwork connections

Solid electrolytes offer high cell resistance and hence electrometers with an input impedance exceeding 1014 Ω are used for the EMF measurements. A literature survey on the measurement techniques revealed hardware details that measure the signals from the cell and send data to the PC through a serial port using signal conditioning and a data processing module.[8–13] The measurements are collected on a PC through data acquisition software.[14–17] Various techniques measure the response of the electrochemical cells. The serial ports for data transmission from the hardware to the PC include RS-232, RS-422, and RS-488.[18–21] The data acquisition software is used to collect the data in a file through a serial port from the hardware and have various features for the analysis of the data to allow the smooth operation.[22–26]

The Instrument Control Toolbox reads the UCSM transfer data by the interrupt way, and the serial port is interrupt by triggering the serial port communication event of Bytes available. The involved steps from the establishment to the end of serial communication are creating serial port objects, setting serial port communication parameters, opening serial ports, reading and writing serial port data, and closing the serial ports.
