> 6.3 | Compiler Flags

> There is only one compiler flag “MUX_MANUAL” for a conditional compile of the driver. With this compiler flag set the driver can be compiled in a special manual version where opening and closing of the multiplexer can be controlled via special DeviceIoControl() commands instead of automatic control via the opened virtual channels. This manual version is used for internal automated module testing and is not relevant for usual driver operation.
