Pyserial 'Access Denied' Error when using shared COM port

I am currently running a python program where pyserial reads incoming serial data to then output given signals with an Arduino using pyfirmata based on that data received. However, this data needs to also be received by tera term. Which creates an issue since only 1 COM port is received.

To get around this, I downloaded HHD virtual serial port tools to create a virtual COM port so both can be used to their respective programs. Even after creating the virtual shared port I still get the access denied error.

For example, I created a virtual port 'COM16' from 'COM14'. If I open COM14 through tera term it reads the correct data but then when I try to run my python program reading from 'COM16' I get a access denied error.

Any ideas on how to get around this?
