See Appendix A for the correspondence between these bits and the respective card types.
C_SEL The currently selected card type as specified in a previous SELECT_CARD_TYPE command.
A value of 00
H
means that no card type has been selected.
C_STAT Indicates whether a card is physically inserted in the reader and whether the card is powered
up:
00
H
: no card inserted
01
H
: card inserted, not powered up
03
H
: card powered up
8.1.2 SET_PROTOCOL
This command is used to control the line speed of the communication channel between
BioCARDKey/BioSIMKey reader and host device. The line speed of the communication is controlled by two
factors, namely, the Delay Factor and the Baud Rate.

DELAY Determines the time delay inserted by the BioCARDKey/BioSIMKey between two
consecutive bytes sent in order to adapt to slower host system speeds. The time delay is
given by N * 0.1msec, with N ranging from 0 ... 255 (00 - FF
H
). The default value is N = 0
(delay changes only valid on RS232 reader).
