Open TCP connection - AT#OTCP
9.2.1
Description
This command directs the CellGO3G to open a TCP connection to the specified TCP server.
Once an IP link is established, the attached host can open a TCP connection at any time (except when
the CellGO3G is already in a process using TCP resources).
This TCP connection can be closed by the remote TCP server or by the attached host by sending an
<ETX> character on the serial port (depending on the AT#DLEMODE parameter).
Note:
-
If AT#DLEMODE parameter is set to 1, the CellGO3G interprets an <ETX> received from the serial
port not preceded by <DLE> as a close request from the attached host. For further information
on <ETX> - <DLE> mechanism, please refer to the chapter describing AT#DLEMODE parameter.
