Command Reference Manual
0 Selects normal speed buffered mode (disables error-correction mode) and forces &Q6
(selects asynchronous operation in normal mode.)
1 Same as \N0.
2 Selects reliable (error-correction) mode and forces &Q5 (the modem will try to negotiate
an error corrected link). The modem will first attempt a LAPM connection and then an
MNP connection. Failure to make a reliable connection results in the modem hanging
up.
3 Selects auto reliable mode and forces &Q5 (the modem will try to negotiate an error
corrected link). This operates the same as \N2 except failure to make a reliable
connection results in the modem falling back to the speed buffered normal mode.
4 Selects LAPM error-correction mode and forces &Q5 (the modem will try to negotiate
an error corrected link). Failure to make an LAPM error-correction connection results in
the modem hanging up.
5 Selects MNP error-correction mode and forces &Q5 (the modem will try to negotiate an
error corrected link). Failure to make an MNP error-correction connection results in the
modem hanging up.
