Since you were sending a fix, possibly I shouldn't comment on this. If so please disregard my
suggestion for a trivial cleanup.

if(a - b <= c && a + b >= c)
if(a <= c + b && a + b >= c)
if(c + b >= a && a + b >= c)
if(b >= a - c && b >= c - a)
true, if:
b >= |a - c|
so
		if (oclose >= abs(obaud - baud_table[i])) {

should work as well

similarly,
		if (iclose >= abs(ibaud - baud_table[i])) {
