Chapter 4 – FTP Services

Multi-Tech Systems, Inc. AT Commands for Wireless Modems with IP Connectivity (S000333B) 28

#FTPPUT Put Data to Server

Definition: This command sent by the attached host directs the TCP/IP stack to connect to the specified FTP

server and to upload the data received on the serial port to the specified file on this server. Once the

operation is completed, the TCP/IP stack closes the FTP connection.

Once an IP link is established, the attached host can send a file to a FTP server at any time (except

when the TCP/IP stack software is already in a process using TCP resources).

This command is similar to a PUT operation (with an automatic connect/disconnect) issued by a

standard FTP client on a PC. The TCP/IP stack handles the global FTP put process by itself.

Note: The TCP/IP stack will interpret only an <ETX> character as the end of the file to be transferred if

it’s not preceded by a <DLE> character. As a consequence, the attached host must send <ETX>

characters preceded by <DLE> characters, and it must also code <DLE> characters as <DLE><DLE>.

Values: Read Parameters:

FTPPUTFILENAME

FTPPUTPATH

FTPPORT

FTPSERV

FTPPW

FTPUN

Syntax: AT#FTPPUT

Command Possible Responses

AT#FTPPUT

Note: Start

sending data

OK_WaitingForData

Note: TCP/IP stack is ready to send data from the serial port to the remote FTP

server. TCP/IP stack then immediately transfers all the data sent by the

attached host to the remote FTP server. To notify the TCP/IP stack that all data

has been sent, the attached host must send the <ETX> character.

<ETX>

Note: Notification from the host for end of data: switches from data to command mode.

Note: The FTP process was successfully completed.

AT#FTPPUT #CME ERROR: 38027

Note: The address of the FTP server has not been resolved by the secondary DNS

server. TCP/IP stack is not able to reach the primary or secondary DNS servers

or a wrong FTP server address has been filled in.

AT#FTPPUT #CME ERROR: <value>

Note: The connection to the FTP server failed. See section ‘Response messages and

error codes’. If an error occurs once the data transfer started, it is preceded by

an ETX character.

#VFTP Display FTP Parameters
