What is the maximum speed I can use for my modem with the Suite?
The highest Speed option you can select in the Modem setup window within !InetConfg is limited in two ways: • The maximum speed of the serial port If you have a Risc PC, you could use 115200. Earlier computers are limited to either 57600 or 19200 by default. However, if you are using a high speed serial card from Intelligent Interfaces or Atomwide, you could use 230400 or 460800 respectively. • The maximum speed of the modem This is determined by the maximum DTE speed supported by your modem and you may be able to find this in the documentation supplied with it. In theory, the highest speed you can use is the smaller of these two values. Note that 56K modems (supporting K56flex, X2 or V.90), seem to require the speed to be set no higher than 57600. However, your computer may not be able to respond quickly enough for reliable transfer at the fastest possible rate: symptoms of this include lots of Bad FCS messages (see the next answer) and low transfer rates in the Internet Suite status
