entering the message, type Ctrl+D to end the message. The SMTP session then enters

into interactive mode requesting media-type, media-subtype, file name, file size and the

attachment body. When the attachment body reaches the file size, another message

displays asking whether to continue with one or more attachments. Type ‘Y’ for more

attachments and type ‘N’ to send mail. Then the email with its attachment is sent to the

to-addresses and cc-addresses configured.

ETX character.

Syntax: Set Value: AT#TCPDLEMODE=<value>

View Value: AT#TCPDLEMODE?

Values: 0 Whe n 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 the end of a connection from the TCP/IP stack. Termination of the TCP or UDP connection will be based on PIO (DTR) or +++ escape sequence.

1 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 belong 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 TCP/IP stack from the Internet are sent to the host through the serial port preceded by a DLE character.

Default Value: 0 Disable

#TCPPORT – Port of Remote Peer Used for TCP Session

#TCPLISTEN – Open a Listening TCP Connection

Description: This command, sent by the attached host, directs the TCP/IP stack to open a listening

TCP connection on the specified TCP port. Once an IP link is established, the attached

host can open a listening TCP socket at any time (except when the TCP/IP stack

software is already in a process using TCP resources).

The TCP connection will be active upon reception of a TCP connection request sent by a

remote allowed TCP peer (TCPSERV) on the appropriate TCP port (TCPPORT). Once opened, this TCP connection may be closed by the remote TCP peer or by the

attached host by sending an ETX character on the serial port (depending on the

DLEMODE parameter). Notes:

The LTCP command can be aborted before an incoming TCP request ha s been received

by issuing an <ETX> character on the serial port.

If the DLEMODE parameter is set to 1, the TCP/IP stack will interpret an <ETX>

character only as a close request if a <DLE> character does not precede it. As a

consequence, the attached host must send <ETX> characters preceded by <DLE>

characters, and it must also code <DLE> characters in <DLE><DLE>.

Syntax: Set Value: AT#TCPLISTEN=<TCP Port Number> Values: TCP Port Number Default Value: None

#TCPSTOP – Close TCP Listening Mode

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 TCP/IP stack software is

already in a process using TCP resources). This TCP connection may be closed by the

remote TCP server or by the attached host via sending an ETX character on the serial

port (depending on the DLEMODE parameter).

Syntax: Set Value: AT#TCPOPEN=<IP Address, TCP Port Number> Values: xxx.xxx.xxx.xxx (format of IP Address)
