ECM RX
Enable or disable error correction mode (ECM). ECM checks for fax data errors and corrects them. To reduce errors on sent faxes,
see ECM TX.

NOTE
ECM must be enabled on both the machine and the other fax device because error check is performed on both the sending
and receiving devices.
Even when ECM is enabled, errors may occur due to telephone line conditions.
It may take a longer time than usual to process data when ECM is enabled because the error check and corrections are
performed while the data is transmitted.
