ESP8266 do support UART1, but please notice that UART1 only has TX, UART0 has both TX and RX. So it is suggested to use UART1 to print logs, use UART0 to do communication work.

You can refer to the ESP8266_RTOS_SDK\example\driver_lib\driver\uart.c to user UART.

UART documentation : http://bbs.espressif.com/viewtopic.php?f=51&t=819.

Thanks for your interest in ESP8266!

I want to use UART1 as debug console (simulates input/output from WIFI) and use UART0 as communication port with function device:
PC console <==> UART1 -- ESP8266 -- UART0 <==> Function Device

Questions:
1. Does RTOS-SDK support UART1 ?
2. How to enable & use UART1 in firmware? any sample code?
3. How to connect Hardware wires/pins?

Many thanks!
