A serial port is an interface that allows a PC to transmit or receive data one bit at a time. It is one of the oldest types of interfaces and at one time was commonly used to connect printers and external modems to a PC.

What devices can be plugged into a serial port?
Mouse - One of the most commonly used devices for serial ports, usually used with computers with no PS/2 or USB ports and specialty mice. Modem - Another commonly used device for serial ports. Used commonly with older computers, however, is also commonly used for its ease of use.
What is serial port and how it works?
In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. ... To interface with these and other devices, USB-to-serial converters can quickly and easily add a serial port to a modern PC.
What does a serial port look like on a computer?
A serial port is male in gender, and has either 9 pins or 25 pins. The shape of the port is slightly D-shaped. A serial computer port may be used for a mouse, external modem, scanner, or other linking software such as for a personal data assistant (PDA). ... Only very old computers have a 25-pin serial port.
Can a serial port be used for a monitor?
In summary, no, a serial port is not a video port and there is no way to use a monitor of any kind with it (even a 9-pin monitor, let alone 15-pin one). Since it does not have onboard video, you will need to install a video-card.
What is 9 pin serial port used for?
DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also they are used on DB9 cable assemblies for data connectivity.
How does a serial port send data?
The serial port takes the byte, and sends it out one bit at a time (a serial bit-stream) on the transmit pin of the serial cable connector. ... To transmit a data byte, the serial device driver program sends a data to the serial port I/O address. This data gets into a 1-byte "transmit shift register" in the serial port.
What is the difference between serial port and USB?
USB allows data to travel on the average of ten times the speed of the normal parallel port. It is also faster than a serial port. The average serial port transfer rate is 150 kbps; the USB port is up to 12 Mbps. USB 2 is forty times faster, with a maximum transfer rate of 480 Mbps.
Why is it called a serial port?
The name "serial" comes from the fact that a serial port "serializes" data. That is, it takes a byte of data and transmits the 8 bits in the byte one at a time. The advantage is that a serial port needs only one wire to transmit the 8 bits (while a parallel port needs 8).
What port is my device using?
All you have to do is type “netstat -a” on Command Prompt and hit the Enter button. This will populate a list of your active TCP connections. The port numbers will be shown after the IP address and the two are separated by a colon.
Is VGA a serial port?
VGA is a graphics interface which uses RGB analog signals as video output. It's technical name is DE15 connector. The common name of RS232 connector is SERIAL PORT. This connector is basically used to connect various components to the PC like mice, printers etc.
Is HDMI a serial port?
The High Definition Multimedia Interface (HDMI) and DisplayPort are both modern serial interfaces for carrying digital video from one product to another over cables. They replace long-running analog interfaces like VGA, S-video, and RGB.
How many pins are on a serial port?
Serial ports consist of two signal types: data signals and control signals. To support these signal types, as well as the signal ground, the RS-232 standard defines a 25-pin connection.
What is DVI used for?
DVI (Digital Visual Interface) is a digital video interface developed by the Digital Display Working Group (DDWG). It is able to support both digital and analogue video signals over a single DVI cable and is commonly found on computers, LCD monitors, projectors and other digital display equipment.
Is DB9 a VGA?
VGA Monitor (DB15 & DB9)
The VGA connector can use a classic DB9 connector or (more commonly today) a DB15 style connector. The female end of this connector is at the Host/PC. ... VGA is an analog standard.
What cable is used for RS232?
The original pin layout for RS232 was developed for a 25 pins sub D connector. Since the IBM-AT, 9 pins RS232 connectors are commonly used. In mixed applications, a 9 to 25 pins converter can be used to connect connectors of different sizes.
