(19) Magnetic stripe write → idle command (Models: 300/310)
General Description
This command writes magnetic data set by the data setting command.
Details of Operation
This writing operation starts only when normal write data is set for all specified write tracks.
If there is no targeted card, it will wait until one is inserted into the device, then begin to write
to the card.
If normal write data is not set to the specified write track, the reader/writer will respond with the
DLE characters to reject the command.
The device automatically verifies the data after magnetically writing.
When the magnetic writing fails, the device will retry to write the data the number of times set
by the write retry count setting command (91h, W). The initial value for the retry count is two
times (initial time, plus 2 times).
