Connection errors are occurring
Action:
1. Check the maximum baud rate for the modem to which you are connecting,
and then change the baud rate to match.
2. If the line you are accessing requires error control to be turned off, do so
using the AT command AT&Q6%C0.
3. Be sure no line interference exists. Retry the connection by dialing the
number several times. If conditions remain poor, contact the telephone
company to have the line tested.
4. Be sure the modem is current and compliant with CCITT and Bell standards.
Replace with a supported modem if needed.
You are unable to connect to an online subscription service
Action:
1. If the line you are accessing requires error control to be turned off, do so
using the AT command AT&Q6%C0.
2. If the ISP you are accessing requires access at a decreased baud rate,
reconfigure the communications software to correct the connection baud rate
to match the ISP.
3. If this does not work, force a slower baud rate (14400 baud) with the
AT command AT&Q6N0S37=11.
You are unable to connect at 56 Kbps
Action:
1. Find out the maximum baud rate at which the ISP connects, and change the
settings to reflect this. Reattempt to connect at a lower baud rate.
2. Be sure no line interference exists. Retry the connection by dialing the
number several times. If conditions remain poor, contact the telephone
company to have the line tested.
