The most common port for a computer to connect to a modem is called a serial port. The most common communication path with a printer is through the parallel port. A computer has several ports that let it communicate with other devices. These devices usually contain a RS232 port to connect them with your computer. A software program called a serial port terminal (SPT) is used to communicate data via a serial port.Ī serial port is a communication channel between your computer and another device. By connecting a PC to a serial port, you can send and receive binary data.

It is a type of digital connection that uses only binary data (0 or 1). With a serial port, you can communicate with other devices, such as modem, a scanner, or another computer. One advantage of unidirectional communication is that only one end is required. Unidirectional communication is where the computer can send commands to a device and then receive data from that device.

Serial communication uses the 8-bit data format and is unidirectional. Serial ports transfer binary data using only binary data characters (0 or 1). If your device has an RS232 interface, Serial Terminal allows you to send and receive ASCII data and control functions, such as toggling or dimming the display, that cannot be achieved with standard HyperTerminal.Ī serial port is a communication channel, typically found on a computer, between that computer and another piece of equipment, such as a modem, a scanner, or another computer.
