Summary:  sscanf(),  If there is a decimal number followed by the character '_' 
 in the buffer, you can't get the the number. 

Original Submission:  I think there may be some troubles with the function 
sscanf(),

Lets have a look at the following example:

void mc(void)
{
    char buf[64] = "<1/dr_2_600";
    int addr,port,speed;

    sscanf(buf,"<%d/dr_%d_%d",&addr,&port,&speed);
    printf("addr=%d,port=%d,speed=%dn",addr,port,speed);
    return;
}

The expecting results are: addr=1, port=2,speed=600.
However,the actual results are: addr=1,port=28600, and 'speed' gets a invalid 
value.
