ubuntu serial port terminal

The chip used by USB serial port converter is PL2303. You can enter the lsusb command on the UbuntuLinux terminal to find the device information # lsusb [root@www.linuxidc.com ~] # LsusbBus002Device001: ID1d6b: 0002LinuxFoundation2. 0roothubBus006Device001: ID1d6b: 000 The chip used by the USB serial

Add the following line to the file to initialize the serial port terminal: 　　 Tty: 2345: respawn:/sbin/agetty ttyS0 9600 vt100 　　 "Tty" indicates the ID of t

learn the MFC process by writing a Serial port helper toolBecause it has been done several times MFC programming, each time the project is completed, MFC basic operation is clear, but too long time no longer contact with MFC project, again do MFC project, but also from the beginning familiar. This time by doing a serial assistant once again familiar with MFC, and

steps are as follows, just need the idea is to set up the serial port device may not be ttyS2, there may be ttyUSB0 or ttyUSB1 and so on, I am here is ttyUSB0 (I use Fedora Core 8). Therefore, it is a good idea to take a look at the files under/dev first.USB to serial port mount model pl2303h1, insert the USB to the

Notebook is not a serial port, so bought a USB to the serial port line. After the driver installation, the Super terminal to try, the development of the Board pass. I am using XP system +vmware, how to make the virtual machine to identify this

A recent attempt to migrate a gateway program from the VxWorks platform to the Linux platform. In the serial port has encountered some problems, here record.First, under VxWorks, use the devs command to view the device: -> devs DRV name 0/null 1/tyco/0 1/tyco/1 2/pcconsole/0 2/pcconsole/1 9 Host: 4/ram 11/vio 4/ahci01:1 value = 0 = 0x0 The source program used the

Suppose there is a development environment, a board, in addition to the serial port, no external access to the output device, no SD card, no network cable, this time if you want to communicate with this board of interactive files, how to do?According to the file Transfer protocol used by modem: Xmodem,ymodem,zmodem classify itXmodem: Simple and general, transmission information Unit is "packet =128b", trans

your needs. However, I think txe allows the program to have more time to fill in the TDR register to ensure that the sent data streams are uninterrupted. TC allows the program to know the exact sending end time, which facilitates the program to control the timing of external data streams. Section 4 In general, the serial port of the stm32 microcontroller is still well understood, and programming is not co
