What is a COM port?
A COM port is simply an I/O interface that enables the connection of a serial device to a computer. You may also hear COM ports referred to as serial ports. Most modern computers are not equipped with COM ports (almost all laptops with serial ports are not in use anymore), but there are many serial port devices still in use that use the interface. Lab instruments, medical equipment, and point-of-sale systems often make use of serial connections.
If you need to work with Serial port over Ethernet or any other Network (TCP/IP, LAN, WAN) use the software from Electronic Team. Serial to Ethernet Connector is a simple solution to share COM port.
So what are COM ports? They are asynchronous interfaces that can transmit one bit of data at a time when connected to a serial device. The COM designation is due to their use as communication ports on IBM compatible computers. In traditional personal computers, COM1 and COM2 were often used to connect a serial port device such as a modem or mouse. Here is what a DB9 COM port looks like.
