How to read responds from wavecom's modem ?

[hasmibaih]

hai,
can you help me how to read responds from wavecom's modem ?
like as when i type "AT" in wavecom modem through hyperterminal, it will respond "ok"
but i use microcontroller in this case and display the respond in LCD

i had done make a program for this case, but it did not complete
the respond is not like as it should be

this is my syntax :

void main(void)
{
char data[32];
int i;
lcd_clear();
lcd_putsf("Hasmi Baih");
delay_ms(5000);
printf("AT+CSQ");
putchar(10);
putchar(13);
for (i=0;i<32;i++)
data[i]=0; //bersihkan variabel
for (i=0;i<32;i++)
{
data[i] = getchar();
if(data[i]==0x0A)//char enter
break;
}
lcd_clear(); 
lcd_puts(data); 
delay_ms(2000);
}

baudrate between microcontroller and wavecom modem is fine, serial cable is ok
because i can using it for sms gateway
but i can not read responds from wavecom modem

help me please
