assume the read message string is stored in a buffer buf already

char buf[100] = "CMGL: 1,\"REC READ\",\"+85291234567\",,\"07/05/01,08:00:15+32\",145,37";
int comma_cnt = 0, i, j;
char msgidx[10];
char msglen[10];

if(strncmp("CMGL:", buf, 5) == 0)
{
// copy message index till comma
for(i=5, j=0; buf[i] != ','; i++)
{
msgidx[j++] = buf[i];
}
msgidx[j] = 0;

i++; // loc after comma;
comma_cnt = 1;

for(; buf[i] != 0; i++)
{
// check for commas
if(buf[i] == ',')
{
// check for 7th comma
if(++comma_cnt == 7)
{
comma_cnt = 0;
strcpy(msglen, buf+i+1);
printf("message index = %s\n", msgidx);
printf("message length = %s\n", msglen);
}
}
}
}
