MAN Port Devices Driver

Posted on  by admin

I -driver Queries the specified network device for associated driver information.d -register-dump Retrieves and prints a register dump for the specified network device. The register format for some devices is known and decoded others are printed in hex. When raw is enabled, then ethtool dumps the raw register data to stdout. The sample code we use to show port I/O from within a device driver acts on general-purpose digital I/O ports; such ports are found in most computer systems. A digital I/O port, in its most common incarnation, is a byte-wide I/O location, either memory-mapped or port-mapped.

Windows device driver information for Prolific USB-to-Serial Comm Port

Prolific USB-to-Serial Comm Port is a network driver produced by gateway technologies. It offers a stylish as well as convenient computer accessory which is used for connecting serial devices which comply with the RS-232 standard to a windows computer which is USB- equipped. It enables bridge connection between a serial port connector situated in one end and a USB plug connector situated on the other end. As such, it is possible for the user to connect with the serial end to the serial port while the USB connector is plugged into the USB port of the computer. The Prolific USB-to-Serial Comm port therefore offers a convenient way for the user to add serial connections to the computer without having to insert a serial card as well as a traditional port. Worth noting is that this device is functional in all operating systems for windows. For this

Outdated Drivers?

Unless you update your drivers regularly you may face hardware performance issues.

To check your drivers you should manually verify every device on your system for driver updates

The Prolific USB-to-Serial Comm Port is compliant with USB specification and supports highly developed power management, for example suspend, remote wakeup and resume operations. The device is ideal for linking modems, digital cameras, card readers, PDAs and cellular phones among other serial devices to the computer. It enables serial connections with a maximum rate of data transfer placed at I mbps. Since USB does not need IRQ resources, it is possible for additional devices to be connected to the system without undergoing any device hassles as well as conflict of resources that plagued similar devices before. This device is also bus powered which means that it does not a battery or a different power supply. Furthermore, it has a plug and play capability which means that all has to do is to install it and it is ready for use. It is highly recommended you run a free registry scan for Windows and Prolific USB-to-Serial Comm Port errors before installing any driver updates.
