Introduction




Serial port programming is a technique that allows you to send and receive data between your computer and other devices through serial ports. Serial ports are physical interfaces that transmit data one bit at a time, using a standard protocol such as RS-232 or USB. Serial ports are commonly used for connecting devices such as modems, printers, scanners, cameras, sensors, microcontrollers, and more.


Serial port programming is useful for many purposes, such as:



  • Controlling external devices with your computer

In this section, I will share some tips and tricks for serial port programming in Windows that can help you create better and more efficient serial port applications. These tips and tricks are based on the Windows Serial Port Programming Handbook, as well as my own experience and research.


How to use the Windows API functions for serial port communication




The Windows API provides a set of functions that allow you to communicate with serial ports in Windows. These functions are divided into two categories: the communication functions and the device control functions. The communication functions are used to perform basic operations such as opening, closing, reading, and writing to serial ports. The device control functions are used to configure and manage the serial port settings, such as the baud rate, the parity, the data bits, the stop bits, and more.


To use these functions, you need to include the header file windows.h in your C/C++ or Visual Basic code. You also need to link your code with the library file kernel32.lib, which contains the definitions of these functions. You can then call these functions in your code using their names and parameters.


For example, to open a serial port named COM1 in C/C++, you can use the following code:



#include


HANDLE hCom; // handle for the serial port hCom = CreateFile("COM1", // name of the serial port GENERIC_READ GENERIC_WRITE, // access mode 0, // share mode NULL, // security attributes OPEN_EXISTING, // creation disposition 0, // flags and attributes NULL); // template file if (hCom == INVALID_HANDLE_VALUE) // handle error


To close a serial port in C/C++, you can use the following code:



#include


HANDLE hCom; // handle for the serial port CloseHandle(hCom); // close the serial port


To read data from a serial port in C/C++, you can use the following code:



#include


HANDLE hCom; // handle for the serial port DWORD dwBytesRead; // number of bytes read char buffer[256]; // buffer for storing data ReadFile(hCom, // handle of the serial port buffer, // buffer for data sizeof(buffer), // size of buffer &dwBytesRead, // number of bytes read NULL); // overlapped structure if (dwBytesRead > 0) // process data


To write data to a serial port in C/C++, you can use the following code:



#include


HANDLE hCom; // handle for the serial port DWORD dwBytesWritten; // number of bytes written char buffer[256]; // buffer for storing data WriteFile(hCom, // handle of the serial port buffer, // buffer for data sizeof(buffer), // size of buffer &dwBytesWritten, // number of bytes written NULL); // overlapped structure if (dwBytesWritten > 0) // data written successfully


To set the serial port settings in C/C++, you can use the following code:



#include


HANDLE hCom; // handle for the serial port DCB dcb; // device control block structure dcb.DCBlength = sizeof(DCB); // size of structure GetCommState(hCom, &dcb); // get current state of serial port dcb.BaudRate = 9600; // set baud rate to 9600 bps dcb.Parity = NOPARITY; // set parity to none dcb.ByteSize = 8; // set data bits to 8 dcb.StopBits = ONESTOPBIT; // set stop bits to 1 SetCommState(hCom, &dcb); // set new state of serial port


For more information on how to use these functions and their parameters, you can refer to the Windows Serial Port Programming Handbook or the Microsoft documentation online.


How to handle errors and exceptions in serial port programming




When you are working with serial ports in Windows, you might encounter some errors and exceptions that can affect your application performance and reliability. These errors and exceptions can be caused by various factors, such as hardware failures, software bugs, user mistakes, or external interference. Some of the common errors and exceptions are:



  • Invalid handle value: This means that the handle for the serial port is not valid or has been closed. This can happen if you try to open a serial port that does not exist, or if you close a serial port without releasing its handle.



  • Read or write error: This means that the read or write operation on the serial port has failed. This can happen if the serial port is not configured properly, or if there is a problem with the data transmission or reception.



  • Timeout error: This means that the read or write operation on the serial port has timed out. This can happen if the serial port is busy or not responding, or if there is a mismatch between the data rates or protocols.



  • Overlapped error: This means that the read or write operation on the serial port has overlapped with another operation. This can happen if you use asynchronous or multithreaded programming techniques, and you do not synchronize your operations properly.



To handle these errors and exceptions, you need to use some error handling mechanisms that are provided by the Windows API. These mechanisms are:



  • The return value: This is the value that is returned by the Windows API functions when they are called. The return value indicates whether the function has succeeded or failed, and what kind of error has occurred. You can check the return value in your code and take appropriate actions based on it.



  • The GetLastError function: This is a function that returns the last error code that was set by the Windows API functions when they failed. The error code is a numerical value that identifies the type and cause of the error. You can call this function in your code and compare the error code with the predefined constants that are defined in winerror.h.



  • The COMSTAT structure: This is a structure that contains information about the current status of the serial port, such as the number of bytes in the input and output buffers, the number of errors that have occurred, and the type of errors that have occurred. You can use the ClearCommError function to get this structure in your code and analyze its fields.



  • The exception handler: This is a block of code that is executed when an exception occurs in your code. An exception is an unexpected event that disrupts the normal flow of your code, such as a division by zero, an access violation, or a memory allocation failure. You can use the try, catch, and finally keywords in C++ or Visual Basic to define and execute your exception handler.



For more information on how to handle errors and exceptions in serial port programming, you can refer to the Windows Serial Port Programming Handbook or the Microsoft documentation online.


How to optimize the performance and reliability of your serial port applications




When you are developing serial port applications in Windows, you might want to optimize their performance and reliability, so that they can run faster and smoother, and avoid crashes and glitches. To optimize your serial port applications, you can use some optimization techniques that are suggested by the Windows Serial Port Programming Handbook. Some of these techniques are:



  • Use appropriate buffer sizes: The buffer size is the amount of memory that is allocated for storing data that is sent or received through serial ports. The buffer size affects how much data can be transferred at once, and how often data needs to be transferred. If the buffer size is too small, data might be lost or corrupted due to overflow or underflow. If the buffer size is too large, data might be delayed or wasted due to unnecessary overhead. To use appropriate buffer sizes, you need to consider factors such as the data rate, the data size, the data format, and the application requirements.



  • Use appropriate timeout values: The timeout value is the amount of time that is allowed for a read or write operation on a serial port to complete. The timeout value affects how long your application waits for data to be sent or received, and how it handles situations when data is not available or not expected. If the timeout value is too short, data might be missed or incomplete due to premature termination. If the timeout value is too long, data might be delayed or blocked due to excessive waiting. To use appropriate timeout values, you need to consider factors such as the data rate, the data size, the data format, and the application requirements.



  • Use appropriate communication settings: The communication settings are the parameters that define how data is transmitted and received through serial ports, such as the baud rate, the parity, the data bits, the stop bits, and more. the quality and compatibility of data transmission and reception. If the communication settings are not matched or configured properly, data might be corrupted or lost due to errors or conflicts. To use appropriate communication settings, you need to consider factors such as the device specifications, the cable specifications, the protocol specifications, and the application requirements.



  • Use appropriate programming techniques: The programming techniques are the methods and strategies that you use to design and implement your serial port applications in Windows. The programming techniques affect the functionality and efficiency of your serial port applications. Some of the programming techniques that you can use to optimize your serial port applications are:



  • Use asynchronous programming: Asynchronous programming is a technique that allows you to perform multiple tasks simultaneously without blocking or waiting for each other. Asynchronous programming can improve the performance and responsiveness of your serial port applications, as it can avoid delays or freezes caused by synchronous operations. To use asynchronous programming, you can use the overlapped structure and the WaitCommEvent function that are provided by the Windows API.



  • Use multithreading programming: Multithreading programming is a technique that allows you to create multiple threads of execution within your serial port applications. Each thread can perform a specific task independently or cooperatively with other threads. Multithreading programming can improve the performance and reliability of your serial port applications, as it can distribute the workload and handle errors or exceptions more effectively. To use multithreading programming, you can use the thread functions and the synchronization objects that are provided by the Windows API.



  • Use error handling mechanisms: Error handling mechanisms are the methods and tools that you use to detect and handle errors and exceptions that occur in your serial port applications. Error handling mechanisms can improve the reliability and stability of your serial port applications, as they can prevent crashes and glitches caused by unexpected events. To use error handling mechanisms, you can use the return value, the GetLastError function, the COMSTAT structure, and the exception handler that are provided by the Windows API.
