This section defines other settings that might be needed or desirable, depending on your modem.
Error correction can be negotiated between two modems to ensure a reliable data link. Error correction
standards include Link Access Procedure for Modems (LAPM) and MNP4. V.42 error correction allows
either LAPM or MNP4 error correction to be negotiated. Modems differ in the way they enable error
correction. Refer to your modem documentation for the error correction methods used with your modem.
Data compression can be negotiated between two modems to allow for greater data throughput. Data com-
pression standards include V.42bis and MNP5. Modems differ in the way they enable data compression.
Refer to your modem documentation for the data compression settings used with your modem.
