That's what I've been told repeatedly. Further, Sun seems to say that a
SS20 or SSclassic only supports serial rates of 38400, while the U1
supposedly supports higher.
Frankly, I hate to say this, but when it comes to certain peripherals,
PCs seem to be somewhat ahead of Suns. Although, the Octanes serial
ports look the best of all (but, I believe it has no parallel port).
