A vswitch is the transportation hub of the campus network system. Its management features determine the overall performance of the campus network. Some Network Management switches do not have default IP addresses, so they cannot be managed through Telnet or Web during initial configuration. At this time, we need to manage the switch through the serial port. Next, we will show you how to use a

The serial port initialization under Uboot is completed in several steps, and there are three serial port-related initialization functions in the Uboot initialization sequence init_sequence[]. Init_baudrate is used to set the baud rate of the serial

retrospect, perhaps I did not notice that 51 single-chip serial port baud rate generator can only use T1, and I have been using T0 as a baud rate generator.Recently began to contact the STM32 series chip, because there is a firmware library for the operation of the underlying register is encapsulated, very close to advanced programming, learning and easy to use, and now many mobile chips are based on the A

In Linux, all the device files are generally located under "/dev", serial 1 and serial 2 corresponding to the device name "/dev/ttys0", "/dev/ttys1", and USB to the serial port device name is usually "/dev/ttyusb0", The operation of the device under Linux is the same as for a file.Serial

I haven't written a blog for a long time. Let's start a new journey from a small program; The latest project mainly uses the Linux system. This article mainly introduces how to set and read the BD + GPS module (um220), which is actually mainly for serial port (UART) operations. /* * gps.c * * um220 test * * Author: Wang Zhengkai /* I used a Ubuntu computer for testing, the

MSComm acts as a serial communication control Program Serial Communication Programming saves a lot of time. It is very easy to add a MSComm control to a dialog box-based application. You only need to perform the following operations: Open "Project-> Add to project-> components and controls-> registered ActiveX controls", and select control: Microsoft Communication Control, version 6.0 to insert to the curr

When using a serial port to debug the Development Board in VMware Workstation, you may encounter some inexplicable problems. Now I will give a brief summary and share it with you. Configurations are divided into virtual machine configuration and linux minicom configuration. The virtual machine module configuration is as follows: Open the virtual machine configuration page. Select Edit virtual machine

Drive your serial port to deal with registers++ ++After the system completes the initialization for entering the C language environment, the first one that can be written in C is the serial portDriver. In the startup Code provided on the lumit website, the serial port driver

[Download source code][Executable program download] I simply put the source code on it. It is only used for learning and communication. The system is not perfect yet. If you make important improvements, you can give me a copy. Thank you. The project requires a simple. Net-based serial port debugging software with the following features: 1. The serial

Linux serial port cannot receive 0x11. solve the problem that c_iflag (termios member variable) is not effectively set in many popular linux serial port programming versions on the Internet, so there is no problem when transmitting ASCII codes, however, 0x0d, 0x11, and 0x13 are lost when binary data is transmitted. No.

This is a good class of files, a lot of places worth learning, specific in multi-threading, events, custom messages, class encapsulation aspects and so on.Remon provides the serial port class URL is: http://codeguru.earthweb.com/network/serialport.shtml,Since has been running for more than 10 years, the original question and answer section listed for so many years, after the user's summary, to supplement an

System environment: Ubuntu 14.04 and Ubuntu 16.04I was the need for the main two, to see the normal serial output, and the serial content of the real-time output to the fileThe next work is mainly two: 1, installation 2, configurationI believe you will be at least operate some of the full line, we are here with Apt-get installation (not the classmate please google a bit)1.

Currently, General laptops do not have a serial port interface. When debugging and debugging the Development Board or other embedded devices, USB to serial port is a good choice, you can debug the Development Board and download files. However, in special circumstances, some burned-in software or debugging software have

Since the first HELLO program has been completed, it indicates that the entire compilation environment is no longer correct. Now, let's prepare a serial port testing program. As the serial port driver development board has been completed, let's take a look at a simple Linux serial
