AAPT has recently made 56K dial-up available. While most modems connect with no difficulty at this speed, there are some models that require you to enter an initialisation string to connect correctly. These instructions list the modems affected, the initialisation strings required and instructions on how to insert these initialisation strings in various operating systems.
