Assuming that 011870 is followed by more than digit, normally, I'd say your
first set is more applicable.
The . in the pattern at the end means any number of digits, followed by a
timeout.
If you know the number of digits, and it is fixed, then you could use
_011870XXXXXXX or similar to avoid the timeout, and begin the Goto
immediately on reception of the final digit.

The X in the second set will match just one digit, and the Goto will be be
executed.

Does that help?
