BAD PROCESSOR CHIPS Does some serial port cards really have bad processor chips ABSOLUTELY Unless you invest in a PCI serial card with a quality processor and chipset you will very likely, at some point, experience either a computer freeze, driver errors, being unable to communicate with your serial device or even a BSo. D. The reason is that most low cost PCI serial cards are designed with a low cost processor which has low cost poorly written drivers, which obviously results in headaches for the user. The Solution. Our Premium RS2. PCI Serial card shown in the image above uses a quality processor MCS9. Mos. Chip TechnologyASIX which provides superior performance and reliability at unmatched data transfer rates. The card adds two high speed 9 pin serial COM ports to any PCI equipped unlike USB based computer with drivers available for DOS, Windows 9. XP, Vista, 7, 8, 8. After installing the downloadable drivers the created COM ports will automatically show up in your operating systems Device Manager as two additional ports. Since these ports are PCI based they can be used as if it was standard built in COM ports. Both RS2. 32 serial ports share same IRQ which saves valuable resources if other expansion cards are used. Easy Plug and Play installation automatically configures the next available COM port and IRQ address. Networking software for DOS and Windows 3. Feb2003 added reference to Lantastic.

XP work with hardware in a different way. While a DOS driver could be created with asm and have direct acsess to ports, it is a bit more complicated in Windows. It is connected with the fact that Windows, unlike DOS, is a multitasking system which makes it impossible to allow every application to directly change the hardware settings, as one application may fail to know about the changes made to the hardware settings by some other application. Actually one can use asm in and out 3. Windows 9x, but it is undesirable due to said above. To create programmes working with hardware under Windows one should use API application programming interface. This interface allows to use Windows system services from application programmes. API realization is at that entrusted to the drivers. Windows Driver Developer Kit DDKis used to create drivers there is a separate DDK for every Windows OS. Besides API one can use IOCTL codes this method was widely used in DOS,but we shall deal with API functions only. Work with hardware under Windows. API standartizes work with hardware. To get access to hardware the following steps are used. Get Handler of the device by calling Create. File with the device name. For more information refer to. Windows SDK Help. To control the device, call an API fuction for this device or send IOCTLinput output control, the latter via Device. Think Psychology Baird 2011 Ebook. IOCtl for more information refer to Windows SDK Help. Xerox 6360 Printer Driver. In Windows all inputoutput ports are presented as files, so work with ports is mainly carried out via io functions of the file Create. File, Close. Handle, Read. File, Read. File. Ex, Write. File and Write. File. Ex. These functions organize the main interface for opening and closing the connection resource descriptor and carrying out readwrite operations. API also includes a set of connection functions which provide access to connection resourses. The usage of the IO file and connection functions allows the application to perform the following tasks Getting the serial port descriptor. Serial port configuration set and request. Reading from or writing into the serial port. Control of the given events set, which could occur for this serial port. Sending the executive instructions to the driver of the device connected with the specified serial port driver call in is required for extended functions execution.
