Universal IP Devices

Set Commands

#FTPPORT – Enter FTP Server Port

Description: To reach the FTP server, the TCP/IP stack software must know the control port of the FTP server used for file transfer.

Note: This parameter should be changed only upon request of your network administrator since it applies to network infrastructure including firewalls, proxy or specific TCP port translation.

Syntax: AT#FTPPORT=<value>

AT#FTPPORT? Read or display the current setting (or AT#VFTP, AT#VALL).

Values: From 1 to 5 digits (each digit between 0 and 9 inclusive).

Numbers above 65,535 are illegal as port identification fields are 16 bits long in the TCP header.

Default: 21

#FTPMODE – Enter FTP Mode

Description:

Define the FTP behavior for file transfer.

Syntax:

AT#FTPMODE=<value>

 

AT#FTPMODE? Read or display the current setting (or AT#VFTP, AT#VALL).

Values:

0 FTP Active Mode

1FTP Passive Mode

Default: 0

#FTPTYPE – Specify Data Type

Description:

Before transferring files from a specified FTP server, the TCP/IP stack software must specify the

 

type of data to be transferred within the FTP session.

Syntax:

AT#FTPTYPE="<value>"

 

AT#FTPTYPE? Read or display the current setting (or AT#VFTP, AT#VALL).

Values:

A – FTP ASCII sessions (Not all products support this option)

 

I – FTP Binary sessions.

 

Note: When this value is set to A, all the data sent by the TCP/IP stack to the FTP server is made

 

of 7 bits characters (NVT-ASCII: the MSB is set to 0). As a consequence binary data containing 8

 

bits characters will be corrupted during the transfer if the FTPTYPE is set to A.

Default:

I
