It is physically not possible to connect on a dial-up connection above 57600 baud - nor can data flow faster than the theoretical 57600 baud simply because this is the upper limit of the beast.


Maybe my memory isn't so great but I thought that's what they said about
previous hurdles (9600).

I believe that for US phones, 9600 is about at the baud limit.

In our country (Australia) the telco officially only guarantees satisfactory results of up to 2400 bps (on a standard phone line).

However, and not to be to pedantic, baud is not the correct term. Modems operate at a certain BPS (bits/sec.), which is not the same as baud. This is due to compression that allows a higher bitrate than baud rate.

Baud/baud rate is the transmission rate between 2 modems measured in bits per second (bps).

But what confuses the picture more is the fact that since there are 8 bits + 2 stop bits in a transmitted word/byte (character), dividing the bps by 10 gives you the number of BYTES/chars trasmitted per second which is also termed bps. (For example, if you are using kinternet in SuSE and look at the Date Rate flow monitor you'll see the rate shown as, say, 4.0kb/s and not 40,000 bps.) Confusion reigns :-).


Cheers.
