Serial port setup

Dear GNU Radio community,

I'm working on a project that requires reading data from a serial port (e.g., COM1) using the File Source block in GNU Radio on a Windows system.

1. How can I configure the File Source block to read data from a serial port?
2. Is it possible to dynamically update the data from a serial port being read during runtime?

Any guidance or suggestions on how to achieve this would be greatly appreciated.

Regards,

Muhammad Anas
