#FTPGET – Download Files from FTP Server
Description: This command, sent by the attached host, directs the TCP/IP stack to connect to the specified
FTP server and to retrieve the specified file from 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 retrieve a file from an 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 GET operation (with an automatic connect/disconnect) issued by a
standard FTP client on a PC. The TCP/IP stack handles the global FTP process by itself.
Note: The TCP/IP stack will signal the attached host of the end of the file that is being
downloaded with a single <ETX> character. The <ETX> characters that are part of the file data
will be shielded as <DLE><ETX>. The <DLE> characters that are part of the file data will be
shielded as <DLE><DLE>. The attached host will need to remove the shielding <DLE>
characters.

#FTPPUT – Upload Files to FTP Server
Description: 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>.
