What are serial port drivers?
For most devices, the Ports device setup class and the Serial function driver provide the functionality required to operate serial ports and COM ports. Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port.
Which devices are connected through the serial port?
Mouse – One of the most commonly used devices for serial ports, usually used with computers with no PS/2 or USB ports and specialty mice. Modem – Another commonly used device for serial ports. Used commonly with older computers, however, is also commonly used for its ease of use.
Do serial devices need drivers?
You only need one device driver in order to achieve both purposes: The device driver is installed with the system so it can vary depending on what hardware is available, providing abstraction.
What are serial ports used for?
A socket that connects to a serial interface (one bit following another over one line). Serial ports are widely used by sensors for data acquisition, and they were standard on early computers for connecting a modem, mouse and other peripherals. Old Macs used the serial port for printers.
Why are serial ports still relevant in Windows?
The only reason that serial ports are still relevant in on Windows these days is because a USB device requires a custom device driver. Device manufacturers do not like writing and supporting drivers, they often take a shortcut in their driver that makes it emulate a legacy serial port device.
What is interaction between user, OS and device driver?
The following figure illustrates the interaction between user, OS, Device driver and the devices: This Kernel-mode device driver includes some generic hardwares which loads with operating System as part the OS these are BIOS, motherboard, processor and some other hardwares which are part of kernel software.
What kind of device is a serial port?
Serial port is a type of device that uses an UART chip, a Universal Asynchronous Receiver Transmitter. One of the two basic ways to interface a computer in the olden days, parallel ports were the other way.
Is the device driver the same as the hardware driver?
In a very common way most term it as only a Driver also when someone says Hardware Driver that also refers to this Device Driver. Device Drivers depend upon the Operating System’s instruction to access the device and performing any particular action.
