Getting Started With PAULMON2

1. Connect the 8051 hardware (power off) to the PC's serial port
2. Start the terminal emulation program
3. Verify the program's settings (port, baud, 8-N-1, no flow control)
4. Apply power to the 8051 hardware
5. Press Enter (so PAULMON2 can determine the baud rate)

If automatic baud rate detection is configured (the default), PAULMON2 will wait for you to press Enter (Return) after power is applied to your 8051 board. It uses this incoming character to determine your baud rate. The result is stored in memory so that the baud rate detection won't need to be repeated unless the memory is erased or overwritten. Once it knows the proper baud rate, PAULMON2 will respond with a message:

It's a good idea to test the RAM memory using the fancy memory editor or the simple editor if a 4k version of PAULMON2 was selected. Once the RAM is writable, try one of the example programs, and then you're ready to try writing some of your own code!
