    "COM1:" is the name used by Microsoft MS-DOS and Windows for the 1st asynchronous serial port on a PC - it has no meaning on an 8051!

    For PC programming, you need to find another forum.

    If you mean the 8051's on-chip UART, there are examples on this site and in the uVision Getting Started guide
