#Serial port on a computer serial
Today, the serial port is seldom used but can be found as a communication device for GPS receivers, LED and LCD text displays, bar-code scanners and flat-screen monitors. Serial Communication is the vital part in the area of Electronics and Embedded Systems. It faster than i2c and subset of SPI protocol. It has a serial I/O port on the microcontroller to interface with peripheral chips. This new technology could transfer data at high rates on the same bus, called a daisy chain. Microwire is a three wire serial communication protocol. Early PCs were fitted with one or two serial ports. In 1998, the Universal Serial Bus (USB) and FireWire introduced faster interfaces. On a PC, serial ports are called COM ports, identified as COM1, COM2, etc. Higher speed communication was needed for serial communication, such as external data storage units. Each package is limited to 1 access (authorize) IP address - you can use it on maximum one computer.

Because many of the pins were unused and were quite bulky, the smaller DE-9 connector became popular. On the windows PC, open up a putty session and setup a serial port connection (click on serial), and specify the name of the port where the serial device is. The serial port uses a nine-pin (DE-9) connector or a 25-pin (DB-25) connector. Panel - Device Manager, select High-Speed USB Serial Port (Com X), right. This standard is used for transmitting serial communication between devices, which are usually called data communications equipment (DCE) and data terminal equipment (DTE). To configure the Serial Port for your device, on your computer go to Control. The I/O address transfers and receives data to and from a peripheral device such as a mouse or keyboard. Each COM position represents an input/output (I/O) and an interrupt request (IRQ) address. 4) Click + next to Port in the Device Manager to display the port list. 3) Click Device Manager in the Control Panel. 2) Click Control Panel in the Start menu. This device is of use for modern computers that do not come equipped with serial ports, but require serial-to-USB converters to allow compatibility with RS-232. System resource configurations are chosen for each port and are identified by COM1, COM2, COM3, COM4, and so forth. converter AX-USB- is used, select the one shown next to USB Serial Port. Normally, a serial port is a male port, while a parallel port is a female port.
