Serial settings

[Stulander]

Is it possible to specify data bits, parity etc? Will I need to use a more advanced serial library? I need 8E1 and I assume by default this uses 8N1.

Sorry, it's been a long time. I believe Arduino supports this by default, please check the Serial.begin reference and the ESP8266 docs. You just have to rebuild the sketch then.
