Actuallt it is bits per second. ... Binary digITbps
Short for bits per second, bps is a measurement of the data transmission speed. bps is an indication of how many bits
that pass a certain point in one second. The larger the bps rate the faster the download and/or upload time will be.
Bps which is short for bytes per second and also sometimes abbreviated as B/s is the same as bits per second, but instead of bits, the speed is measured in bytes. The difference between the two abbreviations is the uppercase and lowercase b. Byte
is data equal to either 7/8 bits depending if it needs error correction (parity). A byte is spelled as byte and not bite.
This link will explain the speed things, why they vary and a ;ot of other info on using a modem.http://www.modemsite.com/56k/what56.asp
I think ther was a tool called netstat that had some handy functions
