Check the maximum baud rate for the modem to
which you are connecting, and then change the baud rate to
match.
If the line you are accessing requires error
control to be turned off, do so using the AT command AT&Q6%C0.
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.
Be sure the modem is current and compliant
with CCITT and Bell standards. Replace with a supported modem if
needed.
