Modem Configuration Strings

For IRC to function correctly, the modem must be configured correctly. The modem is configured using the primary and secondary initialization strings, which are specified during the configuration process. For many modems, the proper initialization strings can be found in Appendix A. This section provides the information necessary to determine the proper initialization strings for modems not listed in this chapter.

To function in a wide array of computing environments, modems have many configuration options. Table 6-2 provides a summary of those settings which are important for compatibility with IRC.
