the MCU, whether the module is ready, whether the MCU can send information to the module, the effective level of the CTS is lowHAYES the RTS in modem, CTS is used for hardware flow control. The meaning of the RTC and CTS of the UART is now usually referred to as the latter, which is used for hard-flow control.RTS, CTS for hard flow control:(now do the serial port use rts/cts must see content, because mtk/)RTS (Require tosend, send request) is an outp
Obtain the serial device name. Obtain the hardware name in the Device Manager.
Introduction: In a serial communication program, if multiple serial ports are connected at the same time on the PC, it is difficult to know which serial port is used when the serial port is opened from the application program, in this case, you must use the

This ar
Hardware driver in Linux system-USB device (on)
There are more and more USB devices, while Linux is still not completely plug-and-play in hardware configuration. how to configure and use Linux is becoming a major problem for us. This article describes how to use and configure the driver and how to compile the driver. For general users, we can clarify the Linux
Question: What ISA Server 2004 is?
Solution: ISA Server 2004 is a firewall solution that integrates advanced application layer stateful filtering firewalls, virtual private networking services, and efficient Web caching services, which can greatly improve network performance and security and maximize your investment in it. Additionally, ISA Server 2004 provides advanced protection for Microsoft products such as Exchange Server, IIS server, and so on.

Lspci-list all PCI devices
Popularization of pci:
PCI (Peripheral Component Interconnect) is a bus standard that connects the motherboard of an electronic computer and external devices.
Common PCI cards include NICs, sound cards, modem, TV cards, and disk controllers, as well as USB and serial ports. The original video card is usually a PCI device, but soon its bandwidth is insufficient to support the performance of the video card. PCI graphics cards

Each type of peripherals is controlled through read/write registers.
On the hardware layer, there is no conceptual difference between the memory and I/O Areas: they are accessed by sending level signals to the address bus and the control bus, then, read and write data through the data bus.
Because peripherals mus
