you need to know which mode do you want and check device jump to the correct mode

After your confirm your transmittal mode

Edit ax99100_sp.c code to your requirement(default is RS232)

For example if you want to test RS485 half duplex so you need to change the code uart mode

//Port1/Port2/Port3/Port4
.uart_mode= AX99100_RS485_HALF_DUPLEX,

You have 4 ports ,so you need to change code port1-port4 uart mode

After edit ax99100_sp.c you can start to build AX99100 driver

#sudo make

Ends of your compiler , driver to the kernel

#sudo insmod ax99100.ko
#sudo rmmod ax99100
