Detailed Description

Implements OP_SERIAL_RECV to read bytes from a serial port.

Behavior:

• Pops max_len (int) and fd (int); reads up to max_len bytes; pushes a string with received data (possibly empty).
• Only supported on UNIX-like systems; other platforms push empty string.

Errors:

• On wrong types, prints an error and pushes empty string.
