overkill. Even if you pre-compose single bits of '0' and '1', at 300
baud that's 3ms each or 24 samples/bit, and you can easily concatenate the
samples in software for almost no CPU or memory overhead. Now a nice
thing would be to try soft decoding!

yes, but if you are unlucky you might get all unsupported cards...
