After loading a couple of example sketches using the Arduino IDE and having problems I decided to reflash the LUA code and get back to a known starting point. I downloaded the nodemcu flasher software. Inside the zip file are two executables, one for 32-bit systems and one for 64-bit systems. Since I'm using Windows10 I tried using the 64-bit version first. After selecting the right COM port the software appeared to re-flash the module and indicated success. However, after resetting it, and trying to connect with PuTTY I only get random characters on the screen. I've flashed the module several times using different baud rates and flash speeds without any success. (I'm using a SparkFun FTDI 3.3V Basic module for a USB interface with my PC.)
What am I doing wrong and what can I do to get the LUA software to work again?

Sorry no one got back to you. More than likly it is the buad rate. Trying switching it down to 9600.

Hopefully you haven't given up by know.

Hi Jeremiah,
The answer turned out to be the 3.3V Sparkfun FTDI breakout board I was using. I've learned since that time that you must use a FTDI which supplies 5V power instead of 3.3V. Both Adafruit and Sparkfun make a USB FTDI cable which works just great.
