I am using a PIC16F88 with external resonator of 4Mhz.

4 leds connected to portb pins and they are flashing in random in time with the internal timer1 and interrupt.

I have a 433mhz transmitter on another device sending :
serout rfmod,baud,[qual, dataout] ' qual = 10 and dataout = 11

I am not sure how to set the serin command on portb.3 to look for an interrupt of receiving this serial data, once received it should turn of a select led on the portb pin.

Any ideas ? or help appreciated please.

Thanks
