Normal serial ports can be tested using standard Linux serial port applications,See ssd201_uart_test. C。
The serial port with flow control is also tested using the standard Linux serial port application ssd201_uart_test.c,You just need to add the RTX to the CTS of the external device, and connect the CTS to the external RTS.
If configured with RS485, you need to specify the enabled GPIO for the RS485 chip in the application, see test/ssd201_rs485_test.c.
