If <param1> is not specified the value of the corresponding parameter <op_code> is
reset to default value.
<param2>

20.1.4 Notes
• The information text response to the read command does not display the password.
• The FTP server IP address and the FTP server name are mutually exclusive. If value for <op_code>=0 is
specified by user, then value for <op_code>=1 is reset or vice versa.
• Some network operators do not allow incoming connections. Due to these limitations introduced by
network operators it is possible to encounter problems using FTP active mode. If the FTP active mode
fails to exchange files, try the passive mode to solve the problem.
• Some network operators do not allow FTPS. In this case the
command (FTP login) will return
a failure response via
URC after an SSL timeout of 30 s.
SARA-R404M / SARA-R410M-01B
• <op_code>=8 is not supported.
SARA-R4 / SARA-N4
• During connection to FTP remote server (via FTP login command) the FTP profile parameters cannot be
changed or reset to factory-programmed values until disconnection takes place (FTP logout). Only <op_
code>=5 (inactivity timeout), and <op_code>=6 (FTP mode), can be updated while the FTP connection is
on the go.
