    Be aware: MNP protocols below 9 will only gain you higher throughput
if you are sending uncompressed data.  Levels below 9 can actually run
30% slower than a non-compressing modem, because they try to compress
the data, and end up expanding it.  Level 9+ does not have
(significantly) better compression, but is smart enough to know when to
leave the data alone.
