Hardware Problems Table 2-19: Modem Problems continued Problem Possible Cause You are receiving connection errors. Your baud rate is too high for the line you are trying to access. The line you are accessing requires error control to be turned off. You are experiencing line interference, or line conditions are poor. You are unable to connect to an online subscription service. The modem to which you are connecting may not be current or compliant with current CCITT and Bell standards. The internet service provider (ISP) requires error control to be turned off. The ISP you are accessing requires access at a decreased baud rate. You are unable to connect at 56 Kbps. The ISP cannot connect at that baud rate. You are experiencing line interference, or line conditions are poor. Possible Solution Check the maximum baud rate for the modem to which you are connecting, and change your baud rate to match. Turn error control off using the following AT command: AT&Q6%C0 Retry the connection by dialing the number several times. If conditions remain poor, contact your telephone company to have the line tested. Be sure that the modem is current and compliant with CCITT and Bell standards. Turn error control off using the following AT command: AT&Q6%C0 Reconfigure your communications software to correct the connection baud rate to match the service you are calling. If this does not work, try forcing a slower baud rate (14400 baud) with the AT command: AT&Q6N0S37=11 Find out the maximum baud rate at which the ISP connects, and change your settings to reflect this. Retry, connecting at the lower speed. Retry the connection by dialing the number several times. If conditions remain poor, contact your telephone company to have the line tested. 2-46 HP Servers Troubleshooting Guide
