(1) Processing outline
a. If card reading occurs during the standby state, a card input processing occurs.
b. When data is read normally, "Sending" is displayed and data is sent to the host system.
The content of the data transmitted is the area specified by the soft switch.
c. After receiving card data sent normally (ID: 11) from the host system, "Card OK" (upper part of LCD) is
displayed.
Then card release (ID: 12) is received from the host system and standby status is restored. ("Card OK"
display disappears.)
