Im using at90can128 MCU and I need to communicate with ESP8266 module through uart.

first problem is that I don't know how to tell the MCU to apply to uart0 (and not to uart1) where there the ESP8266 module is connect.

second problem is, : lets assume i am communicating with the esp8266 module through uart. I want to see an indication of response from the module by led  blinking for example. I tried to blink the led if the reply to the AT command "AT" will be "OK" but I didn't succeed to blink it. here is the code which suppose to blink it
