S9 – Enable PNP functionality for Windows
S9 enables and disables the Windows Plug and Play identification of the terminal adapter.
(default = 1, enabled)
S10 – Lost Carrier To Hang Up Delay (analogue)
S10 sets the length of time, in tenths of a second, that the analogue modem waits before
hanging up after a loss of carrier. This allows for a temporary carrier loss without causing
the local modem to disconnect. When register S10 is set to 255, the modem functions as
if a carrier is always present.
The actual interval the modem waits before disconnecting is the value in register S10
minus 0.6s.
Therefore, the S10 value must be greater than 0.6s or else the modem disconnects
before it recognises the carrier.
Range: 1 – 255 tenths of a second
Default: 14 (1.4 seconds)
S16 – Last ocurred CAPI/ISDN error cause
See Table 6 ISDN causes and their explanation (DSS1) 84 and Table 8 CAPI causes and
their explanation.91
S30 – Disconnect Inactivity Timer
S30 sets the length of time, in tens of seconds, that the modem will stay online before
disconnecting when no data is sent or received. In error-correction mode, any data trans-
mitted or received will reset the timer. In other modes, any data transmitted will reset
the timer.
Range: 0–255 tens of seconds (0–2 550 seconds) See configuration command “idle”.
S36 – LAPM Failure Control (analogue)
Bits 0 – 2 This value indicates what should happen upon a LAPM failure. These fallback
options are initiated immediately upon connection if S48=128.If an invalid number is
entered, the number is accepted into the register, but S36 will act as if the default value
has been entered.
0 Modem disconnects.
1 Modem stays on-line and a Direct mode connection is established.
2 Reserved.
3 Modem stays on-line and a Normal mode connection is established.
4 An MNP connection is attempted and if it fails, the modem disconnects.
5 An MNP connection is attempted and if it fails, a Direct mode connection is
established.
6 Reserved.
7 An MNP connection is attempted and if it fails, a Normal mode connection
is established.(default)
