Data Communication and Host Modes

•Setting the Startup Mode Default (MD) to 3 (UDP) so that a UDP session is entered automatically when the modem registers onto the network. Serial data will be sent to the IP/port specified in S53.

Incoming UDP packets will be processed out the serial port if

•UDP auto answer is enabled (S82=2);

•The destination IP address matches that in S53 (if Friends Mode is enabled, the IP address also needs to be present on the Friends List);

•Or allow any IP is set (AIP=1);

•The modem is in AT mode (not in a current UDP or TCP session).

UDP packet assembly is affected by the values of S50 (PAD Forwarding Time‐out) and S51 (PAD Forwarding Character). Data received in the serial buffer will be transmitted when the idle inter‐character time‐out specified in S50 (in tenths of seconds) occurs or when a character is received that matches S51 (if non‐zero).

UDP Auto Answer

UDP auto answer (previously called UDP half‐open) is set with S82=2. When set, the PinPoint X will automatically establish a UDP session to the source IP address and port of the UDP packet received. The PinPoint X will remain “locked” to this one remote IP/port until no data is sent or received for the time interval defined in the UDP auto answer time‐out (S83). During this session, packets from other IP/port addresses will be rejected, unless *UALL is set. Whether or not an incoming packet will cause the modem to enter a UDP session is always dependent on the S53 and AIP settings.

The Normal UDP Mode (MD3) can be combined with UDP auto answer to cause the incoming serial data to be sent in UDP packets (instead of being treated as AT commands), while allowing sessions to be established from different UDP sources. A UDP session will be initiated either by incoming serial data or by an incoming UDP packet. The session, started by either method, will be terminated when no data has been sent or received for the S82 period. Once the session termi‐ nates, another may be initiated by either means.

When idle, after the time‐out has occurred, the modem is in AT command mode on the serial port, and any valid AT command may be entered during this time.
