15.6. The Auto Delete Function
When the Auto Delete option is enabled, NetLink will delete data
from internal memory immediately after the polling device
acknowledges reception..
Notes:
·
When Auto Delete is enabled, the "Hold End Data"
function must also be enabled. The data release
command must also specify the number of records
that will be included in each read. This will ensure
that data will not be deleted until reception is
acknowledged.
·
Do not invoke Command ^B07 (Continuous Binary
Block Read) while Auto Delete is enabled, because
NetLink will erase data without waiting for the
polling device to acknowledge reception.
·
When Auto Delete is enabled, data cannot be
released according to the Clue Name matched.
·
When Auto Delete is used with ASCII, Binary
Block, or Xmodem data release, data is deleted in
16 kilobyte blocks. Auto Delete will not clear a
block unless all data from the 16K block has been
released. Therefore, if the user releases only part
of a block, resets the partition, and then re-invokes
the original data release command, records from
the partial (undeleted) block will be released again.
·
Auto Delete functions independently for each
command port and for each FTP method. In other
words, Auto Delete may be enabled for menu
driven data retrieval via the Network Port, and at
the same time, disabled for the FTP Push function.
15.7. Zmodem Data Release Mode
When using Zmodem to release data, make certain your
communications program (e.g. ProComm) is set to prompt for a
new file name when downloaded data is stored. This will prevent
the communications program from accidentally overwriting data
from the previous download. When NetLink's Auto Delete
function is enabled, the "prompt for filename" option also prevents
the unit from deleting unread data when ProComm's crash
recovery feature is enabled.
