I'm on Windows 8.1 and I need a program that allows me to send a hex encoded byte array to a COM port on my computer and then receive an ascii string over that same COM port.
I tried the serial monitor that comes with the Arduino software, but it can only send text.
I tried Putty, but once I was connected I couldn't type anything in the console window.
I tried Termite, but it had the same problem as the Arduino serial monitor.
I tried the following batch script, but it could only send data and I can't receive anything:
certutil -decodehex example_dump_1.txt example_dump_1.bin
copy example_dump_1.bin \\.\com8 /b
