SIO2WiFi using ESP8266
for 400/800 XL/XE Atari Homecomputers

Why?: Just for the fun of coding for the Atari.
:-D

"E.T. phone home"


ESP8266.DRV, the LiteDOS-driver for SIO2WiFi

The ESP8266 can be converted to a SIO2WiFi-modem that can be used as modem to access BBSes found on the internet !
The interface I built is R-verter compatible, so the ESP8266 should work with any R-verter supporting software.
(This is a R-verter compatible modem)


I even managed to put one into a SIO-plug, this is a one-off built for me...

ESP8266/Rverter R:Driver:
The ESP8266 is a Wifi-module that can be used as modem to access BBSes found on the internet !
This is an experimental driver for my ESP8266-device, ESP8266 in a SIO-plug, WiFi on the Atari !
The interface I built is R-verter compatible, so the ESP8266 should work with any R-verter supporting software.
The other way around, the driver is R-verter compatible, so it should work with any R-verter and compatible devices too.
It has a built-in Tiny Terminal to get cracking right away.



Get ESP8266 out of the box:
When you buy a new ESP8266 module (do not forget to use the 5volt breakout-adapter) it's on factory defaults.
One of them is doing IO with 115k2 baudrate.
Unusable for the Atari-SIO port, nor is this baudrate available on the Atari.....
So I wrote a little tool to get the ESP out of the box, resetting the baudrate down to 1200 baud.
It uses a clever trick to generate 115k2 IO for the ESP to understand.
Once run, the ESP is ready to be used as 1200 baud modem.
(To be precise, the baudrate is set to 1221 baud. There is a bug in the ESP-firmware making the module go mayhem when you set it to 1220 or less. Do NOT try this !!!)
