There are two ports that can be controlled for serial blocking (simultaneous control of Read and write): One is the opening of the serial port, whether the open function with O_ndelay, the second one can be opened after the serial port through the FCNTL () function to contro

The company's project is close to the end. From the very beginning, the SerialPort has been used. So, let's make a summary. At the beginning of the project, I never touched the SerialPort. I don't know how to get started, such as the most basic portname (communication port), baudrate (baud rate), and parity (parity) databits (Data bit length) and stopbits (Stop bits) do not know, and later, the Internet Google others' experience, know the most basic

After returning more than 1000 posts and judging nearly papers, I took a long breath. Recently, the serial port solution has finally been finalized, and it will soon end. Otherwise, it will take a lot of time and delay is the devil. I found a code for reference. # Include # Include # Include # Include # Include # Include # Define rxd 0 // receive# Define txd 0 // send# Define LSB 0 // The baud rate is adjus

On the topic "sending and receiving short messages via serial port", I will organize some technical questions I have discussed with netizens into the following text. I hope this article will help more friends who are interested in SMS. Because I am a hobbyist and have limited time and money, I have no power to test many models of mobile phones and modules one by one. There may be such errors, and I hope the

Introduction to serial port standard for RS-232, RS-422 and RS-485 1. The origin of RS-232C, RS-422 and RS-485RS-232, RS-422 and RS-485 are serial data interface standards, initially by the Electronic Industry Association (EIA) developed and released, RS-232 released in 1962, named as EIA-232-E, as industrial standards, to ensure compatibility between products o

The following are some notes I made when reading "communications programming for Windows 95", so most of the topics are the same as chapter 3 in this book. some structure and API announcements are copied from VC 5.0 on-line help. These things mainly talk about how to communicate with the serial port on the Win32 platform. it may be helpful for those who understand the
