Hello,
I have problems recieving serial communication with PIC16F88. I'm
using PICC compiler for MPlab.
I have another PIC of the same series transmitting some stuff, and
that reciever PIC can't register any incomming signal.
This is the source file for the tranciever:
########################################
#include <pic.h>

void send(char letter) {

    while (!TRMT) {
        // Delay until sent
    }
    TXREG = letter;
}

void main(void) {
         char x;
        OSCCON = 112;   //4Mhz
        TRISB = 4;      //RB2 - in, RB5 - out
        PORTB = 0;
        TXSTA = 32;     //async mode
        RCSTA = 128;    //usart enable
        SPBRG = 2;      //19.2 kbps

        x = 0;
                TXREG = x;
        RB0 = 0;
        while(1) {
                                x++;
                                send(x);

                RB0 = 0;
        }

}

This is working, becouse I can see a signal on the wire between two PICs.
Here is the code for the reciever. I've made several kinds of debug
info - writing recieved input to data eeprom, and pulling high some of
the PORTA bits:
########################################
#include <pic.h>
char ee_count = 0;
char tmp;

void main(void) {
        OSCCON = 112;   //4Mhz
//I was not sure if I will need interrupts, and some other version of
the same code tried to use interrupts, but it didn't happen neither
        GIE = 1;
        PEIE = 1;
        RCIE = 1;
        ANSEL = 0;
        TRISA = 0;
        TRISB = 4;      //RB2 - in, RB5 - out
        PORTB = 0;
        TXSTA = 32;     //async mode
        RCSTA = 128;    //usart enable
        SPBRG = 2;      //19.2 kbps
        RA3 = 0;
        while(1) {
               RA3 = 1;
               if (RCIF){
                      RA0 = 1;
                      ee_count++; //write on which address in eeprom
                      EEADR = ee_count;
                      tmp = RCREG;
                      EEDATA = tmp;
                      EECON1 = 4;
//write eeprom - this is taken from the pic16 documentation and it is working
                      #asm
                              movlw 0x55
                              movwf 0x18d
                              movlw 0xAA
                              movwf 0x18d
                              bsf 0x18c,1
                      #endasm
                      while (EECON1 & 2){ //eeprom write finished
                      #asm
                               nop
                      #endasm
                      }
                     RA0 = 0;
               }// if RCIF
               RA3 = 0;
        } //main loop
