Linux has very few commercial software, image editing tools, and consumer software, and it cannot run Microsoft applications like Office. In addition, Linux does not support some peripheral devices, such as storage drives, game poles, mouse and speakers, mainly because Linux drivers are not always used for specific products.

Size is the length of the resident memory, which can be obtained using size = _ SS + _ sp/16-_ PSP. Of course, this is also an estimation method, not an exact value. After the function is executed, the exit status information is saved in status. For example, for the above example, rewrite "geninterrupt (0x60);

Because Modem manufacturers are unwilling to disclose their secrets, they refuse to provide sufficient technical information to open source developers to help them create Third-party winmodems drivers. So these widely distributed devices are currently not available under Linux. Previously, Linux support for embedded printers was limited. Most Linux ap
