What are COM Ports and RS232 Ports?
COM Port (Communication Port):
A COM port is a serial communication interface through which information transfers in or out one bit at a time. Traditionally, COM ports are used in many devices to allow serial communication, facilitating data exchange between a computer and peripheral devices like modems, sensors, and industrial equipment.
RS232 Port:
RS232 is a standard for serial communication transmission of data. It defines the voltage levels that correspond to logical one and logical zero levels, the baud rate, and other parameters for the serial port. The RS232 standard is one of the oldest communication standards, widely used for connecting computers and their peripheral devices.
Differences Between COM Ports and RS232 Ports
| Feature | COM Port | RS232 Port |
|---|---|---|
| Standard | General term for serial communication interfaces | Specific standard for serial communication |
| Voltage Levels | Varies with implementation | +/- 3 to 15V for logical levels |
| Usage | General-purpose serial communication | Defined by RS232 standard for peripherals |
| Devices | Modems, sensors, industrial equipment | Modems, printers, communication devices |
