Serila link UART

Connected up spartan lite to 12V pSU with power and both grounds. Lights flashing.
Cant get serial link to responde. Im using 5V TTL converter and confirmed 9600,n,8,1 going into pin 10. Pin 9 stuck at 5V - nothing on scope
Trying GETHW

Never mind I solved. Cable converter didnt like full 5V

Is There a way to read Lambda/AFR over serial?

send “GETDEFINITIONS” this will tell you info about the sensor data format. send “G” to get the sensor data.
