Because of the FCC regulation, 56k connections are limited to a theoretical maximum of 53kbps. That's around 6.625kBps downstream (to the client). This does not include issues related to line noise, possible congestion in the connection(s) of the ISP to the Internet, and whatever overhead TCP/IP and PPP may impose vis a vis connecting directly to some node using, for example, minicom using zmodem or some other similar transfer protocol. A nice way to test to figure out where the bottleneck occurs is to use IPTraf (or some other tool, of course, it's just that I really like IPTraf) to monitor the link while downloading (1) a file that resides on your ISP's server, and (2) a file that resides somewhere else. The first test will allow you to max out your dial-up connection, isolating it from the congestion between your ISP and the rest of the Internet. The second test should show you exactly how fast things are going. --> Jijo -- Federico Sevilla III : <http://jijo.free.net.ph/> Network Administrator : The Leather Collection, Inc.
