Can the int_rda be lost?
I mean:
My program has got 2 interrupts, rs232 and Timer1.

I've got a looping code that executes:

disable_interrupts(INT_TIMER1);
output_a(row-1);

New pic, ccs 4.093.
This code works fine:
#include <16F88.h>

#FUSES NOWDT //No Watch Dog Timer
#FUSES INTRC_IO //Internal RC Osc
#FUSES NOPUT //No Power Up Timer
#FUSES NO ...

RF_Developer in TRIS register 0 make pin as output, 1 as input.
This line is wrong
set_tris_b(0b11111011); //PIN_B2 serial input, others output
Because all pin is set as input except B2 th ...

Also removing the set_tris function the led starts high. Are you sure that i don't need to set tris?

Here is complete program:
#include <16F88.h>

#FUSES NOWDT //No Watch Dog Timer
#FUSES INTRC_IO //Internal RC Osc
#FUSES NOPUT //No Power Up Timer
#FUSES NOMCLR //Mast ...

I also need to use PIN_B3 as output to control a led.
So I use:
set_tris ...
