This is more than just WIP. hetii has started a serprog implementation on the ESP8266 and Stefanct will set up test hardware if that's ready. Till then this will host various ESP-related bits not necessarily related to Serprog.
UART
The default UART requires line feeds to be sent. This can be done by ending every line with '<enter> <ctrl>-j'. A more convenient solution is to use automatic mapping provided by a terminal emulator, e.g.:
picocom -b 115200 --omap crcrlf /dev/ttyUSB1
After boot you should see (at least) the ready message as below. You can test if the UART connection works correctly by issuing AT commands.

WLAN
To connect to an existing network one needs to
- enable client mode
- enable DHCP
- connect to an AP
- optional: test upstream connection
