Notes: Above figures are theoretical maximums. Other factors may affect throughput: phone line quality, network bottlenecks at ISP, overload at server end, etc. Bytes /sec is calculated as 10 bits/sec to account for housekeeping on modem transfers(parity & start & stop bits). Please send any corrections or additions to this table. It's kind of a work in progress
