MODES OF OPERATION
The Reader can operate in either unbuffered or buffered mode. The modes are described below.
The note that follows applies to both modes.
Note
The insertion and removal of the card must be done in a
continuous motion. If not, the Reader may not read the encoded
data properly. In that case, the Reader responds by either
transmitting the ASCII character “E” representing an error, or by
not transmitting any character, which indicates that the Reader
has not detected data and the card was not completely inserted.
Unbuffered Mode
When a card is inserted and removed, a read attempt is made during both insertion and removal.
If the read is successful, data (including the two sentinel characters) is sent to the PC. The data
is transmitted immediately after removing the card and not retained in the Reader.
When operating in the unbuffered mode, the Reader does not need to receive commands from the
host in order to transmit data or status characters, and data, if available; however, the Reader
does respond to an “Inquiry Command” by sending status characters. The inquiry command that
requests the transmission is the ESCAPE (ESC) character followed by “I” (0x49).
