There is no connection to the ELM327 chip. You need to check the connection

Are you suggesting there's something wrong with the physical connection between the car and the chip? When I plug in the adapter to the OBD2 port on the car, there is a series of flashing yellow lights and then it switches to the static red light, which I think is the power. Are there any troubleshooting steps you recommend?
I don't know about the connection to the car. Their is no connection between the computer and the chip.

How can you tell there is no connection? It seems to be getting responses, no?
b'\x7f\x7f\xfd' is just gibberish. You are looking for a question mark. You possibly don't have the RX/TX connected correctly.
Try manually specify the baud and then go from there. Can you connect to the chip via a console?
Any steps you recommend for determining the right baud rate?
See if the manual or datasheet has any hints. Otherwise just try guessing with a serial console application.
It seems that I can open a COM3 connection via Putty, but I don't know where to go from here. The terminal doesn't allow me to input anything...
Do you see any messages?
No, just a solid green cursor.
That seems like the problem then. You should be able to communicate with the chip.
Interesting, what steps should I take from here?

Notes -The car has a crappy battery, I have to start the car before Windows will even recognize the USB device. -I'm not totally sure the OBD scanner supports the car's protocol, if someone knows of one that would, please let me know. -Tried EasyOBD software which fails at Interface Communication -check connections and power. (The reason I mentioned the battery previously. -FORSCAN Software gave similar results, saying "Failed to connect to vehicle" -My laptop doesn't have standard USB ports, I'm using a USB to Type C adapter. -I'm not well-versed in car protocols or things like baud rates, please keep that in mind. -Thanks in advance to anyone that may be able to assist me. :)
