Hello,
The current CAN hardware is different. However, in general: the baud rate in the terminal program doesn't matter, as a virtual COM port uses the maximum USB speed to communicate with the hardware.
The bitrate settings intended for the COM port are designed for a "true" serial interface that is connected via the USB connection.
Okay, for example, for a USB to RS232 converter.
You can set the bitrate for the CAN bus using the appropriate commands in the terminal.
