8N1 is what the modem has to do, included in 33.6 thingy... > > And, 33.6 is the pysical max if your not transfering text files... since > > the compression in a 33.6 modem isn't *that* efficient. > > It's my understanding that it's supposed to compress things that are not > text, and even a little bit things that are already compressed. A 33.6K > modem isn't that efficient compared to what, a 56K, a 28.8K? Well the compression isn't that good, you will get better troughput if you use zlib with a pppd implementation... Anyways, A 56k modem is more of a balanced 33.6 modem with some extra OMPH... you'll get more speed on download and less on uppload.. //Ian Kumlien ____________________________________________________________ Genesis Mailing List - Info & Archive: http://www.vapor.com/ For Listserver Help: <[EMAIL PROTECTED]>, "HELP" To Unsubscribe: <[EMAIL PROTECTED]>, "UNSUBSCRIBE"
