This is not right since my US Robotics Courier I-Modem is a 56k
ISDN-Modem and has definitivly 57600 BpS. The same is vor my
USR 56k Voice Modem. It HAS 57600 BpS.
You're confusing two items. Serial ports can run at 57,600 bits/sec.,
which is a standard serial port speed. The maximum carried by the
digital phone network (including ISDN is 56,000 or 64,000 bits/s,
depending on whether clear channel is used. Those high speed analog
modems, that rely on a digital phone network to deliver speeds above 33K
(and only in one direction) max out at, in theory, 56,000 but often
deliver less, depending on call quality.
