Recently too busy, there is no time to write about the ucos-ii transplant, first of all the work is easy to make a mistake in the knowledge points recorded, about the CTS and RTS. In RS232 the CTS and RTS have a clear meaning, but since Hayes (HAYES) introduced smart Cat (SmartModem) is a bit confusing, but now this meaning for the mainstream, the main chip manufacturers of the UART controller flow control basic use HAYES Modem flow control interpreta

Security Warning: 1.35 billion of ARRIS cable modems worldwide can be remotely attacked A security vulnerability was found in the Wired modem of ARRIS SURFboard. Attackers can remotely attack about 1.35 billion of devices around the world.Security expert David Longenecker explained that a security vulnerability exists in a very popular wired modem produced by ARRIS (formerly Motorola), affecting billions of

After the ADSL installation is completed, you will be waiting for the installation personnel to come to the door for installation. You should know about the installation method. Otherwise, you will not know how to solve the problem if you change the installation method in the future or encounter some minor problems. The installation of ADSL mainly includes: 1. installation of equipment and lines; 2. Installation of software. First, let's take a look at the installation and cabling of ADSL device

In the low-end router using DISP interface to view the corresponding serial port status information, including DCD, DTR, DSR, RTS and CTS, such as five status indicators respectively mean? DCD (Data Carrier Detect-carrier detection) DTR (data Terminal ready, terminal prepared) DSR (data Set Ready), RTS (Request to send) CT S (Clear to send clean send) in these five control signals, DTR and RTS are DTE devices (data terminal equipment, which is the router in the actual application), DSR, CTS and

ModemNowsms requires a connection to an SMSC to interface with SMS and MMS networks. a smsc connection can be a GSM Modem-a GSM Modem or phone connected to a PC serial port (or to a USB port ).(You can connect to your laptop via infrared. My configuration is Nokia 6610 + Dell flexibility 600 m) 2. Configure SMSCThe first step is to configure SMSC settings, which tell the gateway how it connects to the GSM

starting the server. The method is to use the IPXCOPY command on one computer to start the receiver and use the "IPXCOPY file name" command on the other computer for transmission. The file name can be a wildcard character, you can also use the/S option to specify files that include subfolders. Of course there are other methods, so I will not introduce them here. The above is the connection method of LAN. Next we will talk about the Internet method. There are two ways to access the Internet: one

1. you can directly use the ICS shared by the operating system-one machine as the host, which is used to dial up and install dual NICs (so you do not need to purchase additional hubs or switches, you only need to add one more NIC-two computers have three NICs, and make sure that machine 2 needs to access the Internet, machine 1 is the master server ).ICS (Internet Connection Sharing) is a shared Internet service built into Microsoft Windows 2000/XP. When using this service, you only need to chec

Call data using mobile phones There are countless types of mobile phones in the current market, but most of the mobile phones with data transmission capabilities use a common communication method to communicate with the data MODEM in mobile phones or network providers. The Linux abstract Control Model (ACM) is designed to

This article includes common classic problems in broadband sharing. You can take a look at any questions about network sharing! 1. What are the benefits of shared bandwidth? Now, broadband networks have been activated in many places, and the network speed is greatly improved compared to that of the ordinary MODEM in the past, while the network bandwidth required for browsing web pages and chatting on the Internet is not high, if you just want a comput

CommEvent attribute contains the latest event or wrong numeric code, you can read the CommEvent attribute value in the program to understand the communication status. The OnComm event is closely related to the CommEvent attribute and used together. When any OnComm event or error occurs, this will change the CommEvent attribute value. In the OnComm event processing process, you can determine the CommEvent attribute value. For different attribute values to be transferred to different event proces

We know that the use of RS-232C protocols is well-developed in some areas of electrical and mechanical, and the basics of this are also described in previous articles. So as a supplement, we next to the RS-232C protocol interface signal to a comprehensive summary. I hope this will help you. RS-232C protocol standard interface has 25 lines, 4 data lines, 11 control lines, 3 scheduled lines, 7 standby and undefined lines, commonly used only 9, they are RS-232C protocol interface signal (1) Contact
