Teensy 3.2 and ESP8266

[linuxsable]

Hi. I'm trying to use your library with the Teensy 3.2 and the DIYmall ESP8266 ESP-01S.

I can get the ESP8266 connected up to the Teensy successfully via serial. What happens is the example program from your library compiles with no errors, but it's like it actually never successfully runs on the device.

Steps:

• Compile and upload the below program
• See that there are no compilation errors
• Open the serial monitor on 9600

Expected: "setup begin" and other messages to show in the console. Also, the LED to blink, showing that the loop is actually running.

Actual: Nothing gets logged to the console, no LED blinks, showing that the loop() is never entered.

If I comment out the ESP8266 wifi(Serial1) line, the LED blinks and the loop() is entered. Otherwise it fails silently.
