[SOLVED] hyper terminal and 8051 communication issues

hello friends i am a newcomer to 8051 programming
i cannot program in assembly
only C
i have written a code which would take input from keyboard(on pc) and display the characters on lcd connected to an 8051 uc

here are the key snippets of the code
*************************

void USART_Write_String ( unsigned char *str ){

while( *str ){
SBUF=*str++;
while(!TI);
TI=0;
} return;
}



unsigned char USART_Read_A_Char ( void )
{
unsigned char ch;
while(!RI);
ch = SBUF;
RI = 0;
return ch;
}



unsigned char *string1="hello pc\0";
unsigned char *string2="send the data\0";
unsigned char *test="I AM ALIVE\0";
unsigned char ch[2];
USART_Init_9600(); /*for initialization of uart sets ti ri tcon scon values
Lcd_Init(); /*lcd initialzation
SenStringToLcd(1,test); /*displays on lcd
USART_Write_String (string1); /*displays on hyper terminal
while(1)
{
USART_Init_9600();
USART_Write_String (string2);
ch[1]=USART_Read_A_Char();
ch[2]= '\0';
Delay(500);
SenStringToLcd(2,ch);
Delay(500);




void SenStringToLcd ( unsigned char lineNo, unsigned char *lcdStr ){

if (lineNo==1){
SendCommand(0x80);
while ( *lcdStr ){
SendData(*lcdStr++);
}
}
else if (lineNo==2){
SendCommand(0xC0);
while ( *lcdStr ){
SendData(*lcdStr++);
}
}
else {
}
return;
}


HERE's the problem


i get "hello pc send the data" on hyper terminal
iget "i am alive" on my lcd
when i type any character the send any data again appears conforming that the uc has accepted the data but nothing appears on my lcd where have i gone wrong.
i attached the entire code just in case

you are receiving the data from hyper-terminal ok then you should convert that data in to ascii and display that data
because the received data will be in hex format

err... does anyone have the code for hex to ascii conversion i used a more rudimentary appproach 30=0 31=1 and so on it seems stupid
an algorithm might be a lot easier

//---------------------------------------------------------------------------//
// Function : convert_asciil() //
// Parameters : //
// Input : number to be converted //
// Output : returns //
// Description : Routine converts number to ascii //
//---------------------------------------------------------------------------//


unsigned char convert_ascii(unsigned char temp)
{

return((unsigned char)(temp>=0x0a)?(temp+0x37)temp+0x30));

}
