KwikNet Universal File System Interface

C.4 Using the MS-DOS File System

When used with AMX 86, the KwikNet Universal File System (UFS) interface supports

the MS-DOS

file system. No customization is required. All file devices, including

RAM drives, hard drives and floppy drives, are accessible through the UFS interface.

AMX 86 includes a component called the PC Supervisor which permits AMX 86 to be

used with MS-DOS on PC platforms. Special care must be taken when using the PC

Supervisor with AMX and KwikNet as described in Chapter 3.7.1.

The PC Supervisor Task must be of lower priority than tasks which use it to access

MS-DOS. This requirement leads to the following recommended task priority order

when using KwikNet components such as an FTP client or server or the HTTP Web

Server.

PC Supervisor Clock Tick Task Highest priority

PC Supervisor Keyboard Task

KwikNet Task

FTP server task

HTTP Web Server task

FTP client task

PC Supervisor Task Lowest priority

Note that the order of priority of servers and clients may have to be adjusted to reflect the

relative importance of each of these services in your application.
