This Unix C code monitors a web server every few minutes by trying to retrieve its home page. It sends you email When it can t connect, and every so often while the server is still down. It sends a final message When it comes back up. If you have email paging, just direct the email to your pager address.

FPFilter is a sample disk filter driver that demonstrates how a disk failure prediction filter driver could be implemented. A failure prediction filter driver can predict When a disk may fail and notify the disk driver stack of this condition.

REMOVE removes a TSR. It takes two command line arguments. The first is the name of TSR to be removed (or an * to remove the last one), and the second is a file name which MUST contain the interrupt vectors to be loaded When the TSR is removed.

CBC下写的串口编程，API函数实例 I wish this site had been around When I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.

This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated When the PS/2 start bit is received, at which time the firmware will begin its receive routine. In addition to this interrupt, every 168ms a timer overflow interrupts the main program and implements one state of the mouse state machine. This state machine handles sending bytes to and translating bytes received from the PS/2 mouse automatically. All of this is done in the background while the main program runs in the foreground. The only operation that the main program implements is sending mouse data to the PC via USB.

DSP音频处理示例The benefits of real-time analysis provided by DSP/BIOS are often required in programs that were engineered without it. When the program is not built from the ground up using the DSP/BIOS kernel and real-time analysis features, the lack of familiarity prevents engineers from reaping the benefits of this very powerful tool set, especially in the final stage of development When real-time analysis is needed most. This application note provides an example of the necessary steps required to utilize DSP/BIOS features in order to bring these solutions to bear in an existing application.

Introduction to GPS ToolKit Pro 1.0 GPS ToolKit Pro is an ActiveX object that makes it easy to add GPS support to any Visual Basic, Visual C++, Delphi, Excel, or scripting project that supports ActiveX controls. GPS data (including lat/lon, speed, course, altitude, and dozens of other datasets) can be accessed through GPS ToolKit s properties, and GPS ToolKit s multithreaded event-based architecture notifies your application When data has been updated, saving you from having to write messy polling routines.
