I’m trying to send an ascii string through win10 serial port.
I tried through Teraterm software with not problem.
This device receive ascii character and turn on LED.
I was able to open the port and flush it ATEasy 2023,and get an handle with ComGetHandle.
But I when I try to set the port with ConSetup command or send ascii string with ComSend I get an error. I also tried with debug with but got the same errors.
The code is here.
