AVR, UART, Proteus simulation, not all data displayed on virtual terminal - c

Question

I am writing a code for a MCU until that will transmit data via UART (RS232).
[ATmega8A]
Currently, I am testing my code in Proteus:
#include <avr/io.h>
#include <avr/interrupt.h>
#include <util/delay.h>
#include <stdlib.h>
#include <compat/twi.h>
#define FOSC 16000000 //Clock Speed
#define BAUD 9600 //Baud rate set to 9600
#define MYBRR FOSC/16/BAUD-1
void USART_Init (void)
{
UBRRH = (MYBRR >> 8); //Code for setting
UBRRL = MYBRR; //the baud rate
UCSRB = (1 << RXEN) | (1 << TXEN); //Enable receiver and transmitter
UCSRC = (1 << URSEL) | (1 << UCSZ0) | (1 << UCSZ1); //Frame format setting: 8 Data, 2 Stop bit
}
/* USART transmit function */
void USART_Transmit(unsigned char data)
{
while(!(UCSRA & (1 << UDRE))); //Wait until transmit buffer is empty
UDR = data;
}
/* USART receive function */
unsigned char USART_Receive(void)
{
while(!(UCSRA & (1 << RXC))); //Wait until data is received
return UDR; //Get the data from buffer and return it
}
and the test code in main:
int main(void)
{
unsigned char c;
while(1)
{
a = USART_Receive();
c = 10;
USART_Transmit(c);
_delay(10000);
}
}
In Proteus, the virtual terminal displays 0. However, I am expecting to see 10.
This is just one example, in general only the last digit/character is getting displayed on the virtual terminal.
I cannot explain this. Proteus bug or logic error?
Thank you for any advise.

UART data is sent only in ascii format...you have to convert the integer data to ascii format..use itoa() or do this one
int main(void)
{
unsigned char c;
unsigned char b;
while(1)
{
a = USART_Receive();
c = 10;
b=c;
b=c/10;
USART_Transmit(b+48);
b=0;
b=c%10;
USART_Transmit(b+48);
_delay(10000);
}
}
