5. software function settings:

When the SET_EN is set at low level, after 10ms it enters the setup state. When the SET_EN is set high level, after 100ms it enters the working state. Fixed 9600, 8N1, the software settings are saved if power off.

Read the current parameter. For example, the initial channel is 0 channel, even parity, and shows as follows:
