I heard a rumor that the modem <-> phone <-> modem was a syncronous connection. In this case, there would be only 8 bits, no start or stop bits. a 14.4K connection would then have raw data rate of 1.8K/sec. This would tend to make sense, since I commonly average 3.0K-3.3K/sec connected at 26.4K or 28.8K (3.3K or 3.6K/sec raw data rate). -- Zach Heilig -- zach@gaffaneys.com A horse without a nose... never wins.
