Using C++builder to develop serial communication programs under Win9x is a common headache for programmers, not only to understand many complex API functions, but also to master multithreaded programming. Thankfully, some companies have developed tools for C++builder to write serial communications programs, such as the Moxa Company's Pcomm (which can be downloaded at http:\www.moxa.com.tw), thus helping us

This class library mainly includes: serialbean. java (interface with other applications), serialbuffer. java (used to save the buffer for data received from the serial port), readserial. java (the program that reads data from the serial port ). In addition, this class library provides a routine serialexample. Java as an example. The following sections describe these parts in detail. Serialbean Serialbean is

The definition of serial port, please know for yourself.C # operation serial communication in. NET powerful class library, only three steps are required:1 Create2 Open3 Send/Receive1 Create:1 The required namespaces for serial communication are as follows:using System.IO.Ports; using System.IO;2 declared as a global variable because it is used globallyPrivate New

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. They use USB to expand the

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. Serial Port protocol plug-in type and conversion

Serial Data acquisitionThis document describes how to obtain the serial port raw data and parse the raw data into data that can be processed or displayed.First, the serial port collection has many ways:1), MFC has a special control, direct programming acquisition, a control can only collect a serial port, and the

The last article to tell you about the serial port programming some of the basic knowledge. Today, we are going to introduce a simple example of serial port programming. This example can help you to have a general understanding of the basic knowledge of serial communication. The first is to look at the interface: A bit like a chat software, in fact you can thin

Label:In the actual work, will inevitably encounter serial number generation problem, the following is a simple sequence number generation function (1) Create a custom serial number configuration table as follows: --Custom Sequences Create TableS_autocode (PK1VARCHAR2( +)Primary Key, AtypeVARCHAR2( -) not NULL, ownerVARCHAR2(Ten) not NULL, InitcycleCHAR(1) not NULL, Cur_sernumVARCHAR2( -) not NULL, ZERO_FLG

Device network has become a consensus and inevitable trend. In order to get higher efficiency and strive for competitive advantages, the establishment of a networked system has become a top priority. The Application of serial port card is the earliest in the computer, the external interface is the RS-232 interface, and then extended to the RS-232 and RS-422, RS-485 interface form. Figure 1 Serial Port prod

Today I learned the serial communication experiment under wince. The following is a summary: 1. Device File Name: the device file name prefix consists of three uppercase letters used to identify the special device file name corresponding to the special flow interface driver. The file name prefix is stored in the key value of the corresponding driver in the registry. Such as COM (serial driver) and ACM (audi

Familiar with serial programming should be difficult .. Net is easier, and no nonsense. Let's get started.1. virtual serial port SoftwareBecause there is no serial port hardware on hand, I found a vspm virtual serial port software on the Internet, which is said to be free of charge.: Http://www.skycn.com/soft/30517.htm

Serial port itself, standard and hardware?The serial port is the physical interface of the serial communication on the computer. Computer history, the serial port has been widely used to connect computers and terminal equipment and a variety of external devices. Although the Ethernet interface and USB interface are als

When you need to install SQL Server again, if the serial number is not found, you can try to retrieve the serial number from the installed instance, because after the installation of SQL Server, the serial number (Product Key) is stored in the registry; MSDN Subscriptions Download the installation package is a built-in seria
