That is what ) is that data being read or written is exchanged with other hardware, and some synchronization is needed.The alternative is to look at the data flow being written to the device and use special sequences as control commands.This latter technique should be avoided because it requires reserving some characters for controlling purposes; thus, the data flow can't contain those characters.If You tried to install the drivers from Your installation disk and it didn't installed properly, so there is probably an error mark on the Device Manager.Right click on the name of that driver there and via menu click on Properties/Driver/Update Driver/Browse my computer for driver software and on that coming page click on Browse to search the drivers from the right folder.System calls must have a well-defined number of arguments because user programs can access them only through hardware "gates,'' as outlined in "User Space and Kernel Space" in Chapter 2, "Building and Running Modules".
