Problema puertoCOM PIC16F877A Hyperterminal envio de recepcion y envio de datos

[rmca]

Hola, Necesito ayudaaa urgenteee
El problema es el siguiente:

Me piden que mediante Hyper terminal y un pic 16f877a logre que al presionar una tecla en hyperterminal, el pic lo reciba y me envie un mensaje,( por ejemplo al presionar F me mande el mensaje FEDERICO) hemos hecho un codigo, pero no logramos que aparesca nadaa en la pantalla de hyper, dejo anexo el codigo haber si alguien puede ayudarnos , gracias

Parece que el PIC y la Hyperterminal no estan programados en los mismos parametros. Saludos.
