The default value is 30 s.
<FTP_mode> Number FTP mode:

• 1: enable SSL encryption of FTP (control connection or data connection)
<USECMNG_profile> Number USECMNG profile (number). Defines the USECMNG profile which specifies the SSL/

no profile is set a default USECMNG profile is used (see USECMNG section).
<timer_trigger> Number Enhanced direct link sending timer trigger (in milliseconds); valid range is 0 (factory-
programmed value), 100-120000; 0 means trigger disabled.
<data_length_
trigger>
Number Enhanced direct link data length trigger in bytes, valid range is 0 (factory-
programmed value), 3-2048; 0 means trigger disabled.

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

21.1.4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 +UFTPC=1 command (FTP login) will return
a failure response via +UUFTPCR URC after an SSL timeout of 30 s.
