How to change TrueRNGPro mode under Windows

[Mouscap]

Most of my question is already in the topic.
I try to change the mode by using a batch file with the “Mode” command like this :

Mode Com4: Baud=110 Parity=N Data=8 Stop=1
Mode Com4: Baud=300 Parity=N Data=8 Stop=1
Mode Com4: Baud=110 Parity=N Data=8 Stop=1
Mode Com4: Baud=4800 Parity=N Data=8 Stop=1

But no effect…

Mouscap,

We use a python script to change the modes. Check out this blog post: https://ubld.it/how-to-use-truerngpro-with-python-in-windows-10-and-linux/

If you scroll down a bit to the example script the mode change is happening around here:

print('================== Debug Mode ====================')

# Put the TrueRNGpro in Debug Mode

# Knock Sequence
ser.baudrate = 110
time.sleep(0.1)
ser.baudrate = 300
time.sleep(0.1)
ser.baudrate = 110
time.sleep(0.1)

# Set Mode
ser.baudrate = 2400 # debug mode
time.sleep(0.1)

# This clears the receive buffer so we don't print binary data
ser.flushInput()
ser.flushInput() 
returnline = ser.readline()
ser.flushInput()

# This labels our columns for readability
print("RNG1 RNG2")
print("_____ _____\n")

# Loop
for _ in range(debugloops):
 try:
 returnline = ser.readline() # Read a Line from the TrueRNGpro
 print(returnline) # Print the result to the console
 except:
 print('Read Failed!!!')
 break

print('================== Normal Mode ====================\n')

# Return back to Normal Mode

# Knock Sequence
ser.baudrate = 110
time.sleep(0.1)
ser.baudrate = 300
time.sleep(0.1)
ser.baudrate = 110
time.sleep(0.1)

# Set Mode
ser.baudrate = 300 # normal mode
time.sleep(0.1)
ser.flushInput() 

# Set Data Terminal Ready to start flow
ser.setDTR(True) 

# This clears the receive buffer so we aren't using buffered data
ser.flushInput()
