yeah, i should've mentioned, that's function i use to check the sum,
not compute it. return b instead, or just patch the buffer inside the
function:
void
oncore_add_checksum(char *buf, int len){
unsigned char b;
int i;
b = '\0';
for(i = 2; i < len - 3; i++)
b ^= buf[i];
buf[len-3] = b;
}

GDB has a 'break' feature; why doesn't it have 'fix' too?
