RS232 voltage levels:
Positive = Network coverage.
Negative = No coverage.
Tip: Flow control (AT\Q) will override this indication, so if you want to
use CTS to indicate network coverage, flow control has to be off
(AT\Q0).
*NUMTOIP=n
Convert 12 digit number to IP.
• n=0 : Use as name.

*PPPNOCARRIER=n
Provides a “No Carrier” message to a device connected to the
serial port using PPP or CHAP when the cellular connection
becomes unavailable.
• n=0 : Disabled (Default).
• n=1 : Enabled.
TCP
This group includes commands specific to TCP serial commu‐
nications.
Figure 1-8: AceManager : TCP
S0=n
This register determines how the PinPoint X responds to an
incoming TCP connection request. The PinPoint X remains in
AT Command mode until a connection request is received.
DTR must be asserted (S211=1 or &D0) and the PinPoint X
must be set for a successful TCP connection. The PinPoint X
will send a “RING” string to the host. A “CONNECT” sent to
the host indicates acknowledgement of the connection request
and the TCP session is established.
