Chapter 15 – FTP Client 

Multi-Tech Systems, Inc. MultiConnect Serial-to-Serial Adapter User Guide (S000354A) 

 

 

This scenario describes the receiving of a file from the FTP server:  

a)   With Automatic Authentication enabled by specifying a few authentication details: IP address of the 

device and a valid login name 

b)   Data connection in ACTIVE mode. 

The MultiConnect IP establishes a control connection to the specified FTP server, 
automatically checks for the configured values, and logs into the FTP server. If the 
user is a valid user, the MultiConnect IP prompts the host device to enter the 
Password shown here: 

Password: **** <CR> 
 

If successfully logged in, the MultiConnect IP sends a message and prompts the 
host device to enter a Filename, and then it sends a message as below: 

Connected 
Filename: filename <CR> 
size = <filesize from server> 
Press <CR> to receive file 
<CR>  

------ File Transfer ---- 

When the complete file is received, the FTP session responds with OK. 

By default the data connection is in active mode. The client sets the data transfer 
mode as ‘BINARY/IMAGE’ during the file transfer. 
Note: If the '-p' option is specified in the command, the data connection will be in 
passive mode 

set ftp machine <ip-address/host-name> login <user-name> 

ftp -r [-p] ip-address 

OK: FTP session closed

 

 
 

The host can abort the FTP session by issuing “Ctrl+C”  at any given time. 

 

The host can abort the file transfer by issuing “Ctrl+C” with a delay of 3 seconds. The file into which 
data was written will be deleted by the client, and the data connection will be closed. 

 

The serial device has to read and store the data received. It has to implement timeout mechanisms to 
come out in cases where the network is prone to errors.
