I have an issue with stty config and reception of data in FX30:
1- I send the data from my host : echo -ne “test\r” > /dev/ttyUSB0
2- I receive data in module side with: cat /dev/ttyHSL0
3- But for the first test ( first echo), I don’t receive “test” and some stty flags have changed in the module side ( like ixon - isig - opost) !!
4- i resend the data from my host : echo -ne “test\r” > /dev/ttyUSB0 == this time i receive the second “test” !!!
have you an idea for this behaviour?
