Then there is the issue Almost every modem supports V42 error correction, which makes the modems speak a sort of synchronous with each other (actually data is transmitted in blocks with a start-of-block and end-of-block marker, and a checksum). That gets you 8 bits in a bith minus some negligeble V42 overhead. So an 28k8 modem can actually transfer almost 3.6 Kbytes/sec. Because of the block-oriented approach you do get a bit higher latency on interactive connections, which is why gamers often turn of V42. Somehow, nobody seems to know this.
