Linux serial port I/O mode As we all know, in Linux, all devices exist in the form of files, and the serial port is the same. Generally, I/O operations are implemented in two ways: blocking and non-blocking. The concept of "timeout" is actually a processing method in blocking, and it is actually a blocking I/O mode. I

1. Configure Comm.jar. Comm.jar is a sub implementation of the low-level interface of the API, call the local DLL file, because Java itself does not have the ability to directly access hardware settings, are implemented by invoking the local method. It can be downloaded from the official website of Java. After downloading, the Comm.jar package is imported into the engineering classpath. Put the other two very important documents Javax.comm.properties and Win32com.dll into your engineering dire

The biggest advantage of managing vswitches that can be managed through a serial port is to solve many default IP addresses of vswitches. vswitches are the transportation hubs of the campus network system, and their management features determine the overall performance of the campus network. Some manageable vswitches do not have default IP addresses, so they cannot be managed through Telnet or Web during in
