Multi-Tech Systems, Inc. AT Commands for Wireless Modems with IP Connectivity (S000333B) 49

Command Mode / Data Mode for TCP Services: ETX is a character

When DLEMODE is set to 0, no specific process is needed on [ETX] characters.

It means that it is not possible for a host to request an end of connection or to receive a clear indication of end of

connection from the modem.

Socket TCP service :

TCP socket through

AT#LTCPSTART or

AT#OTCP

ENTRY FLOW

Enter in DATA mode:

The “Ok_Info_WaitingForData” message

sent to the host on the serial port indicates

the entry in DATA mode.

The modem is ready to receive the data

from the host. This data will be sent to the

remote TCP peer.

Exit DATA mode:

1. The host can't end the DATA mode.

2. The modem ends the DATA mode if an error

occurs or if the TCP peer disconnects by

sending a message to the host (this

message is not preceded by the [ETX]

character)

Socket TCP service :

TCP socket through

AT#LTCPSTART or

AT#OTCP

OUTPUT FLOW

Enter in DATA mode:

The “Ok_Info_WaitingForData” message

sent to the host on the serial port indicates

the entry in DATA mode.

The modem then immediately sends the

data received from the remote TCP peer

to the host.

Exit DATA mode:

1. The host can't end the DATA mode.

2. The modem ends the DATA mode if an error

occurs or if the TCP peer disconnects by

sending a message to the host (this

message is not preceded by the [ETX]

character)

Socket TCP service :

TCP socket through

AT#LTCPSTART or

AT#OTCP

When DLEMODE is set to 1, the [ETX] character means a request or an indication of end of

connection.

As a consequence, [ETX] characters that belongs to the payload data must be sent by the

host on the serial port preceded by a [DLE] character.

Similarly [ETX] characters received by The modem from the Internet are sent to the host

through the serial port preceded by a [DLE] character.

[ETX] is CTRL+C in a keyboard.

[DLE] is CTRL+P in a keyboard.
