First derived from espForth_44 by Albert Lu, Sam Suan Chen, Chen-Hanson Ting on 22 sep 2017.
1. ignore WIFI and UDP
2. ignore tone() since not yet implemented for ESP32.
3. add input line echoing.
4. modify COLD at the end to call .OK stead of CR.
5. modify .OK to print one more space.
The back slash "" and the left parenthesis "(" are comment words. All the messages after back slash and between parentheses will be ignored.

\ to set wifiboy led pin as output direction (led on), enter the following:
2 ( output ) 10 ( led pin gpio# in hex ) pinSel
\ set led pin level high to turn off led.
1 ( high ) decimal 16 ( led pin gpio# in decimal ) pinOut
\ set led pin level low to turn on led.
0 ( low ) 16 pinOut
\ change number base to hexadecimal.
hex
\ define led as constant 0x10 (gpio #16).
10 constant led
\ define off as constant 0x1.
1 constant high
\ define on as constant 0x0.
0 constant low
\ define W to wait for a while.
: wait FFFFF for next ;
\ define off to turn off led.
: off high led pinOut wait ;
\ define on to turn on led.
: on low led pinOut wait ;
\ define blinks to blink given number of times.
: blinks for aft on off then next ;
\ blink 5 times.
5 blinks
