Both ```Serial``` and ```Serial1``` objects support 5, 6, 7, 8 data bits, odd (O), even (E), and no (N) parity, and 1 or 2 stop bits. To set the desired mode, call ```Serial.begin(baudrate, SERIAL_8N1);```, ```Serial.begin(baudrate, SERIAL_6E2);```, etc.
#### Progmem ####
The Program memory features work much the same way as on a regular Arduino; placing read only data and strings in read only memory and freeing heap for your application.
The important difference is that on the esp8266 the literal strings are not pooled. This means that the same literal string defined inside a ```F("")``` and/or ```PSTR("")``` will take up space for each instance in the code. So you will need to manage the duplicate strings yourself.
#### WiFi(ESP8266WiFi library) ####
This is mostly similar to WiFi shield library. Differences include:
