remote modem:

0 Clear data buffers and send break to remote modem.

1 Clear data buffers and send break to remote modem. (Same as 0.)

2 Send break to remote modem immediately.

10.6.3 \Nn - Operating Mode

This command controls the preferred error correcting mode to be negotiated in a subsequent data

connection. This command is affected by the OEM firmware configuration.

Command: \Nn

n Decimal number which corresponds to the selected mode.

0 Selects normal speed buffered mode (disables error-correction mode). (Forces

&Q6.)

1 Serial interface selected - Selects direct mode and is equivalent to &M0, &Q0 mode

of operation. (Forces &Q0.)

Parallel interface selected - Same as \N0.

2 Selects reliable (error-correction) mode. 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. (Forces &Q5, S36=4, and S48=7.)
