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
1 FTP 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
