#include <reg51.h>
#include "_LCD_R8C.c"

#define INPUT_LENGTH 11


int main()
{
char input[INPUT_LENGTH]; /* The input from the serial port */
int input_pos = 0; /* Current position to write in the input buffer */

lcd_init();
lcd_clear();

SCON = 0x50;
TMOD = 0x20; /* timer 1, mode 2, 8-bit reload */
TH1 = 0xFD; /* reload value for 2400 baud */
TR1 = 1;
TI = 1;
RI = 1;

while(1)
{
/* read the next character from the serial port */
if(input_pos < INPUT_LENGTH) /* check for buffer overflow */
{
input[input_pos] = getCharacter();
lcd_print_b(input[input_post]); /* only makes sense to print each character once */
input_pos++;
}
}


char getCharacter (void)
{
char chr /* variable to hold the new character */

while (RI != 1)
;

chr = SBUF;
RI = 0;

return(chr);
}

I am not able to find out the mistake .. I want to know where is the mistake?

Please put your code within the code tags. It's clear as day within the textbox that you are typing in.

How do you know that getCharacter() is not getting 255 from SBUF?

What have you done to try to debug your program?
