PIC-16F877. Problem to receive data.

[Jan]

Hi

I'm working on a project with PIC-16F877 . I have made a program where I send and receive data between the PIC-16F877 and Hyperterminal on a computer. Everything works ok when I use baud-rate 9600, but when changing the baud-rate to 57600 the PIC-16F877 can only send data!!! The program in PIC-16F877 stop when it is supposed to receive data(getc).
I'm using a 11 Mhz crystall.

1. Use an interrupt-driven software receive fifo, instead
of just using getc(). CCS has an example file for this,
called EX_SISR.C.
It's in this folder: c:\Program Files\Picc\Examples
<BR>
2. Use an 11.0592 MHz crystal, instead of an "11 MHz" crystal.
<BR>
3. Use the ERRORS directive in your RS-232 statement. Example:
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
<BR>
4. Make sure you are using the Hardware USART. This is on
pins C6 and C7 on a 16F877.
<BR>
5. If it still doesn't work, then use a different terminal
program than HyperTerminal.

through the hyperterminal i have created.please help me..it's urgent.
