Async Serial + Socket Bridge

Hard Python Concurrency
Solve this problem

Write a Python script that asynchronously reads data from a serial port and forwards it to a TCP socket client. Use asyncio for concurrency.

Constraints

  • Must use asyncio, not threads.
  • Serial read must be non-blocking.
  • TCP server port fixed at 9000.
  • Forward every received byte without modification.
  • Stop when client disconnects.
  • Assume pyserial-asyncio is available.
