Hello to all

I thought of making a small quite simple interface but that does not turn(shoot) as I want.
The program is realized in PBP3 and the PIC is programmed with one pickit3.
I use a PIC16F1825, chosen as its programmable internal clock to 32MHz and I make him(it) turn(shoot) in 16MHz with the internal oscillator.
A port RS232 TTL receiving "words" (in 100Kb/) representing the width of the impulse to take(bring) out on one other pine of the pic
The entrance(entry) RS232 is on Rx, I use the instruction Hserin, I put a temporary billposter LCD, information arrives well at the pic.
The problem is in the management of the timer.
I have impulses got out of it but the width does not really depend on the mass received(successful) word of command(order).
I know that I could use the "pulsout" without using the timer but it is not possible in my case because the information arrives too quickly in RS232 and I do not have time to receive information, to handle(treat) them, and to take out again them if I do not use the timer.
Have you a track(runway)??
Thank you in advance
