Set the Error Correction Mode

Error Correction Mode (ECM) prevents loss of data due to poor phone lines by
detecting errors that occur during transmission and automatically requesting
retransmission of the erroneous portion. Phone charges are unaffected, or might even
be reduced, on good phone lines. On poor phone lines, ECM increases sending time
and phone charges, but sends the data much more reliably. The default setting is On.
Turn ECM off only if it increases phone charges substantially, and if you can accept
poorer quality in exchange for reduced charges.
