Functionality

After booting, the IP Module initiates a RAW TCP Auto-dial-in session to the configured server, depending on the

configured Auto-dial-in trig mode settings. If chat-script negotiation is enabled, then the data transfer starts only after

successful chat-script negotiation, other wise the data transfer starts right after the connection establishment. Data

from network to serial gets transferred as it is without any modification. Data from serial to network gets filtered

according to the applied filters , and only the data, not matching any of the filters ,will be sent on to network , the rest

of the data is discarded. If at all a timer is enabled, then even the successful data will be discarded until the

elapsation of the configured amount of time, to maintain a gap of atleast the configured amount of time in between

two successfully sent messages. In chat enabled mode, the data with "auto-dialin-delimiter" will be prefixed with

"auto-dialin-prefix", otherwise the data is sent as it is on to the network.

Notes

• Once the PPP link is up with an IP address, auto dial-in session can be probed.

• Simultaneous multiple Dial-in sessions are not allowed.

• Switching between the Command Prompt and the Dial-in session in RAW mode is not possible.
