What is serial port programming?

Answer 1

to connect a series of devices

Answer 2

A serial port is any port that transmits and receives data serially, or one piece at a time. This is as opposed to a parallel port, which can transmit and receive data along multiple paths at the same time. RS-232, USB, FireWire, PS/2, and ADB are all examples of serial ports. In common usage, the term "serial port" is usually used to refer to RS-232 ports.

Answer 3

serial and parallel are legacy network ports, from way back when before eathernet and usb were adopted as standard. they were both used extensively for printer interfaces, but have since been superseded by usb. in the pre-usb days, specialist hardware such as detectors or motor controls would connect to the parallel port, and if two computers required direct networking they would be connected on serial.

Answer 4

A serial communication port is one that transfers the bits of a byte/word one at a time over the same line. This avoids signal skew problems and reduces the amount of wires needed in cables.There are many different ports using serial communication that have been used on computers:

• RS-232, used to be on practically all computers but now generally considered obsolete
• USB
• Ethernet
• Firewire
• Thunderbolt
• Fibre Channel
• HyperTransport
• MIDI
• etc.
