 Actually, sometimes it can. Some USR Courier modems, for example, support
the DTE speed of 230400 bps (although I'm not sure if this speed is really
useful even when connecting at 56000/V90).

 Only zip archives ? ;-)) Actually, almost all modern modems use data
compression protocol (MNP5 or V42bis, for example). And while transferring
the uncompressed data (plain text etc.) at high speeds using V90 it's easy
to achieve very high CPS (theoretically, 56000 bits per second = 7000 bytes
per second; using V42bis at uncompressed data - apporx. 14000 CPS). The
real speed, surely, will be much lower.

Why?
