Mell What devices connect to serial port?
The serial port is a type of connection on PCs that is used for peripherals such as mice, gaming controllers, modems, and older printers. It is sometimes called a COM port or an RS-232 port, which is its technical name. If that’s not enough to confuse you, there are two types of serial ports — DB9 and DB25.
What still uses a serial port?
serial communications are still very used in microcontroller projects like Arduino and some ohers. It’s a very reliable and easy to debug communication interface. Even if the physical ports itself don’t come by default on most recent computers, we have to acquire usb to serial converters to interface with the devices.
Are serial ports obsolete?
The serial port used to be found on almost all new PC’s but not anymore. Thus as of 2008, it’s becoming obsolete, if not already obsolete. It’s often called a “legacy” device, but it’s still used by some for hardware designed to connect to the serial port especially for computers used as servers by companies.
What is the most common serial port?
A serial port is an interface through which peripherals can be connected as a communication channel using a serial (bit-stream) protocol. Usually, a serial mouse is connected to COMI (communication port 1). The most common type of serial port is a 25-pin D-type connector carrying RS-232 signals .
What are characteristics of a serial port?
Serial Port Characteristics. The following values represent the typical range of communications characteristics for serial ports: baud = 110, 300, 1200, 2400, 4800, 9600, 19200, or 38400 bits/second. #bits = 5, 6, 7, or 8 (data bits) parity = n (none), e (even), or o (odd), parity bit.
What does serial port stand for?
serial port. (hardware, communications) (Or “com port”) A connector on a computer to which you can attach a serial line connected to peripherals which communicate using a serial (bit-stream) protocol. The most common type of serial port is a 25-pin D-type connector carrying EIA-232 signals.
How do serial ports work?
Serial ports rely on a special controller chip, the Universal Asynchronous Receiver/Transmitter (UART), to function properly. The UART chip takes the parallel output of the computer’s system bus and transforms it into serial form for transmission through the serial port. In order to function faster,…
