Serial port programming for Windows and
How is serial port programming used today?
Serial programming is an important subset of application development when you are interacting with external devices through serial ports. It is concerned with serial communication, which is the sending of data sequentially over a communication channel or computer bus. Sending and receiving data between a peripheral device and a computer requires you to use serial programming methods. The device can range from a printer or keyboard to a portable cryptocurrency wallet or a remote surveillance camera. The complexity of the routines required will depend on the type of port you will be using. RS232 programming for older ports interacts with the hardware layer whereas when programming for USB you will be interacting with a complete software stack.
The Windows operating system is a prime target for applications due to its tremendous popularity. Windows serial port programming deals with the COM ports of the operating system through which all data flows in and out of the computer. Many languages can be used, but C is one of the main languages used for this type of programming. You will be called upon to use the WIN32 API and depending on your application may need to delve into the TAPI Windows telephony interface.
Linux is another very popular operating system with many variations in specific implementations. Your serial ports are named differently in Linux, with names such as /dev/ttys0 and /dev/ttyUSB0, so right away there are differences in how you approach Linux serial programming. C again is a popular language choice for serial programming and you will be interacting with devices that Linux treats as files. You will be using an API such as termios to communicate between your application and the serial ports.
The specialized nature of serial port programming may be outside the scope of your team’s expertise, and problems in communication between your application and its intended target devices can lead to a crippling delay in your development project. Problems such as unexpectedly corrupted text or connectivity issues can be hard to diagnose for programmers without extensive serial port experience.
