Cannot dial into operating
You can connect to IRC, but attempts to dial into the server’s operating system fail.
Explanation: If an incoming call is not positively identified as destined for Integrated Remote Console, the call is forwarded to the operating system. Integrated Remote Console uses its configured initialization strings to reset the modem after it regains ownership. If these initialization strings are not compatible with the initialization strings used by the operating system, the modem may not return data in the format which the operating system expects. This is typically a problem with the response code format. Windows NT, for example, configures many modems (but not all) for numeric response codes. (V0). If the configured initialization string in IRC does not specifically contain the command to configure the modem for numeric responses, the modem returns to its default state which is usually verbose responses. As a result, the operating system may be returned a verbose connect string like:
“CONNECT 38400/V34/LAPM/V42BIS/33600:TX/33600:RX”
when it is expecting a numeric code like “17.” For incoming calls to be processed correctly, the modem must be configured identically by both the operating system and IRC.
Solution: Reconfigure IRC’s communication settings to more accurately match those of the operating system.
■Make sure that IRC’s primary and secondary initialization strings are compatible with how the modem is used by the operating system. See Chapter 6 for more information on modems and Appendix A for suggested initialization strings.
