serial port listener

Do not often contact computer friends may be a lot of small computer knowledge do not understand, today's editor in the QQ group of computer enthusiasts have found a friend asked a relatively simple, but the novice friends generally do not pay attention to the problem: what is a serial disk, what is the same port hard drive. Whichever speed is faster and so on. The author found that a lot of friends do not

MFC production host computer, the first thing to understand is the serial port programming, there are generally two methods, one is to use ActiveX control, such as MSComm serial port control, there is a serialport class or some other serial

Previously, when I was playing gec2410, I had the idea that I was debugging it in Linux. Because the target board is powered or the serial port sent to the PC during the reset, this was already implemented in windows, so I wanted to see the results in Linux, but after setting up a serial port in Linux, I found no respo

This article describes the VC serial port application, share for everyone to reference. The specific usage analysis is as follows: Serial port as the most basic computer communication I/O interface, its use although less on the PC, but in the field of industrial instrumentation is still quite common, so that they firs

Minicom is the Linux under the serial communication software, its use relies entirely on the keyboard operation, although no "HyperTerminal" so easy to use, but after using the habit reader will appreciate its efficiency and convenience, the following will explain the installation and configuration of minicom.First, install Minicom:use the following command: # sudo apt-get install minicomwhat Ubuntu is doing right now is that it's quite practical and

How do you want to buy a computer or assemble a computer, you first need to know some hardware knowledge, in this article for you to specifically introduce the serial port and the hard disk, and the difference between the two. I hope to help you. In order to facilitate understanding, you can understand the difference between the serial and the hard drives: Coll

I recently summarized three methods of reading and writing through the serial port (COM:The 1st method is to use a serial control launched by Microsoft in. net2.0. the SerialPort class must be. net2.0.The 2nd method is to use APIs to write serial communication. Although it is difficult, you can easily implement the var

About javax. Comm About javax. CommJavax. Comm is an extension API provided by Sun for developing independent communication applications on the platform. (PS: Here, javax's X accurately shows that it is an extension package, rather than a core package. But for historical reasons, not all of javax's extension packages are, for example, swing packages are already part of Java's core architecture. However, to be compatible with Java coding, javax is still used. swing .) Javax. Comm can access the R

When we learn the principles of the microcomputer, many people will have a big problem with some interface bus. These are some of the content contained in the serial port protocol. So in order to better understand some interface serial port protocol standards, we will give a detailed introduction to such problems.

In the previous article, you should know which interface your printer uses. After connecting the printer to the computer using the data cable, select the appropriate port in the driver to print it. The following describes the serial port printer driver operation steps. 1. Select the correct port number in the driver. Y

Two independent asynchronous serial I/O ports are provided for the UART unit of the high-efficiency FIFO serial port based on the implementation of b0x (clock frequency: 60 MHz) on the ARM7, each communication port can work in the interrupt or DMA mode. That is, UART can generate an internal interrupt request or DMA re

Point:1. Serial Port and comport are physical interfaces (hardware ). While TTL, RS-232, RS-485 refers to the level standard (electrical signal ). 2. Generally, only Gnd RX Tx is connected to the device. Do not connect to the VCC or + 3.3v power cord to avoid power supply conflicts with the target device. 3. The pl2303 and cp2102 chips are USB-to-TTL serial ports
