Record the experiences of debugging serial port device bugs and debugging serial port bugs It took almost one day to get a Bug. The Bug is as follows: This Bug is especially unique. It is reported every time the end user uses the software without any prompt on the development computer. I carefully thought about the newly added features in the source code and did not find any obvious problems. Therefore, t

C ++ port scanner and Port ScannerI. Principle The principle of port scanning is very simple, that is, to establish socket communication and switch over the port without passing through the connect function. If it succeeds, it indicates the port developer; otherwise, the

Share it with you for your reference. The details are as follows: Recently, due to work requirements, the above requirements need to be reported daily O M of hundreds of

MAC OS is essentially a UNIX system, and UNIX systems are mostly non-root users that are not able to use a common port less than 1024 by default. At this time if you need to use 80 ports in your development, such as Tomcat, for example, Vitualbox An HTTP service has been built and you need to do some system port forwarding if you want to access it directly from the browser's localhost (without the ":

Tags: LTE iptable download default SM BSP Use command toolbar connection numberWhether iptables or TC (traffic control) is powerful, it is a network-related tool, so we use these two tools to limit the bandwidth of the port.1. Use the command ifconfig to view the network card information on the server, such as the network card eth0 is used for external networks, that is, the user through the network card to connect to the system, then we will be limit

In the Last Post, "LTE Physical Transmission Resources (3)-time-frequency resources," the final mention of Pcfich and other downstream physical channels, this blog post originally wanted to write Pcfich channel, but in preparation for writing Pcfich, found the need to use the antenna port related content, and these content is not yet written. So this paper first write the antenna port and downlink reference

Port Basics Encyclopedia + common Port Control Port Basics Encyclopedia of Knowledge 1) Accepted ports (well known Ports): from 0 to 1023, they are tightly bound to some services.

This indicates that port 80 (which is the Tomcat listening port) has been occupied by other programs. First, run the "netstat-ano" command to display the port status, and then find the port in the result, then, search for the corresponding program in the display of the input "tasklist" command based on its PID, And you

The 16c2550 serial port chip can be used to expand two serial ports. Its operation method and register usage are exactly the same as 8250, so we can use the classic 8250 driver in Linux to drive st16c2550. 8250 the driver remains unchanged. You need to add the 16c2550 initialization code. In the initialization code, you need to set the chip selection and IRQ pin for 16c2550, configure the read/write timing for the 16c2550 peripherals (setup, pulse, cy
