GL 868 Dual V3

I am using `Telit modem GL 868 Dual V3`. AT command `AT#SCFG` has 2 parameters- packet size to be used and data sending time-out for `TCP`. Is there any AT command which specifies that if any delimiter string is found, then that data will be sent on `TCP` ignoring the packet size and time-out?

SCFG only used to set parameters of socket, where probably you can specify maximum possible size of your data. I suggest it to keep highest number. But the actual command for sending data #SSEND uses delimiter ctrl-z to send data and esc to cancel sending data. If you are using binary format to send data then its advisable to use #SSENDEXT.

Thanks for your reply.
But I am connecting my modem to the remote server in online mode connection and not in command mode connection. Hence, I do not use AT#SSEND to send data.
This parameter is set using AT#SD command. When I send any data on the serial port of the modem, it is sent over TCP by the modem according to the socket parameters set through AT#SCFG (number of bytes received on serial or Time-out). I want that if any particular delimiter string is received on the serial port, then the data will be sent over TCP ignoring the parameters set by AT#SCFG.

In transparent mode, it will not be possible as I see it. You either have to go with SSEND approach or stick with the limitation of online mode.
