Case Communications Mayze 24, Reference Manual, Page: 102 / 166

–E0
Error correction disabled. Default.
–E1 Error correction is enabled according to V.42. The
modem will auto-detect the format of error correction
used by the remote modem. If the error correction
handshake times out without detecting error correcting
ability in the remote modem then the modem reverts to
standard data mode (no error correction).
–E2
MNP error correction is enabled in Reliable mode. The
modem will only accept a call from a modem using
MNP error correction (classes 2-5). If the modem fails
to establish MNP error correction, the call is
disconnected.
–E3 MNP error correction is enabled in Auto-Reliable
mode. The modem accepts calls from the remote
modem regardless of whether MNP error correction
(classes 2-5) is used or not. If the modem fails to
establish MNP error correction, it reverts to its normal
operation.
–E4
LAPM error correction is enabled in Reliable mode.
The modem will only accept a call from a remote
modem using LAPM error correction. If the modem
fails to establish LAPM error correction, the call is
disconnected.
–E5 LAPM error correction is enabled in Auto-Reliable
mode. The modem accepts calls from the remote
modem regardless of whether LAPM error correction is
used or not. If the modem fails to establish LAPM error
correction, it reverts to its normal operation.
Note that if using error correction on a leased line, MNP requires
–E2
at both ends, but LAPM requires
–E4
at both ends.
