- its a little bit over 28.8kb/s due to mnp4/v42 stripping out start and
- stop bits out of the data connection. they [the modem advertisers] keep
- advertising modems with outragous compression ratios, thats where you
- get the 115kb/s, where the truth is almost everyone uses some kind of
- zip/arj compression.. no one in the real world downloads plain ascii
- text, and in order to reach the theroritical compression ratio you
- hafto be downloading a really really huge text file with just the
- letter A repeated over and over.. its never that high with real data
