Version: DM562P-MA-P01
July 12, 2000
Bit Value Function
2,1,0 = 0 Modem hangs up.
1 Same as 5.
2 Reserved.
3 Same as 7.
4 Modem tries to connect using V.42
Alternative Protocol (compatible wit
MNP levels 2 - 5). If handshaking fails,
modem hangs up.
5 Modem tries to connect using V.42
Alternative Protocol compatible with
MNP levels 2 - 5 ). If handshaking fails,
modem tries to connect using a
standard asynchronous connection.
6 Reserved.
7 Modem tries to connect using V.42
Alternative Protocol (compatible with
MNP levels 2 - 5). If handshaking fails,
modem tries to connect using a
standard asynchronous connection and
automatic speed buffering.
Register S46: Protocol selection.
Register S46 defines the protocol selections specified
for future negotiation.
Value Function
136 LAP-M only.
138 LAP-M with adaptive data compression –
default.
Register S82: Break handling
Register S82 specifies the break signal method used
during V.42 applications. The break type to be used
depends on the user application.
Value Function
3 Expedited break signaling, regardless of its
sequence in data sent and received by each
modem. Data integrity maintained both ahead of
and after the break.
7 Destructive break signaling, regardless of its
sequence in data sent and received by each
modem. Data not being processed by each
modem at time of break is discarded.
128 In sequence break signaling as data is sent and
received. Data integrity is maintained both
ahead of and after the break.
Register S97: Energy detection threshold
This register can use in Call Progress Mode (CPM)
mode, for dial tone detect threshold. The default value is
2. This register determines the detection threshold for
Call Progress (CPM) tones. The default value is 2.
