Set Break Control: Defines what action the modem takes when a break (attention
signal) is sent or received, as described below.
n = 0–5
In connect state, transmits break to remote (if in reliable mode):
n = 0, 2, 4 Enter command state, but does not send a break
n = 1 Destructi ve/expedited
n = 3 Nondestru ctive/expedited
n = 5* Nondestru ctive/non-expedited
In command state, transmits break to remote (if in reliable mo de):
n = 0, 1 Destructive/expedited
n = 2, 3 Nondestructive/expedited
n = 4, 5* Nondestru ctive/non-expedited
In connect state, receives break at serial port (if in di rect mode):
n = 0, 2, 4 Immediately sends break and enters command state
n = 1,3, 5* Immediately sends break through
In connect state, receives break at modem port and sends to serial
port:
n = 0,1 Destructive/expe dited
n = 2, 3 Nondestructive/expedited
n = 4, 5* Nondestru ctive/non-expedited

Set Operating Mode: Determines the type of connection attempted by the modem.
n = 0–4
n = 0, 1 Buffer ( Normal) Mode — no data compression or error correction,
but uses speed buffering.
n = 2 MNP Reliable Mode — the modem attempts to negotiate a n MNP
error-correction ‘reliable’ link, hanging up if it fails.
n = 3* V.42 Auto-Reliable Mode — i f V.42 detection is enabled (-Jn), a
LAPM or MNP link can be detected and negotiated; otherwise, on ly
LAPM is attempted. If configured for -J0 and a protocol connection
is not made, the modem hangs up. If configured fo r -J1 and a pro-
tocol connection is not made, the modem falls back to speed b uffer-
ing mode.
n = 4 V.42 Reliable Mode — the modem attempts to negotiate LAPM er-
ror correction, hanging up if it fails.
\O none
Originate Reliable Link: In buffer (normal) mode (\N0 or \N1), the modem attempts
to originate an MNP link, regardless of whether the modem originated or answere d
the telephone call (physical connection). The remote modem must answer the MNP
link request for the link to be established (refer to the \U comman d that follows).
