SERIAL PORT ABCs
The serial port is an Asynchronous port which transmits one bit of data at a time, usually connecting to the UART Chip. Serial Ports are commonly found on the majority of PC Compatible computers. Usually referred to as a DB9 or DB25 connection, both of which adhere to the RS-232c interface standard and defined in ISO 2110 and ISO 4902. The number 9 / 25 indicating the number of pins found on the connector. DB9 Serial connections are now commonly found on modern PCs where DB25 is commonly found on older computers.
SERIAL PORT DEVICES
Below is a listing of various hardware components which can be purchased and used with your Serial port.
Mouse - One of the most commonly used devices for serial ports, usually used with computers with no PS/2 Ports or laptop computers.
Modem - Another commonly used device for serial ports. Used commonly with older computers, however, is also commonly used for its ease of use.
Network - One of the original uses of the serial port, which allowed two computers to connect together and allow large files to be transferred between the two.
Printer - Today, this is not a commonly used device for serial ports (not applicable to the DB25 or Parallel Port). However, was frequently used with older printers and plotters.
