The control characters for the communication via the Flash Control Interface (FCI) of the USC-2 card depend on the interface (Telnet or RS-232) and on the defined communication mode (A, B or C). The control characters define what is necessary to send to the card and also the return from the card (refer to the see tables 3 and 4). With the FCI commands LFLF and CRCR you can choose the mode. Here are some important notes:
•Default mode of the USC-2 card is mode A, but mode C is recommended, to avoid communication problems when SAMLight is running.
•Mode B cannot be stored on the USC-2 card.
•Starting SAMLight enables LFLF.
•Closing SAMLight restores previous LFLF sate.
•Starting PCMode (visible server) disables LFLF and CRCR.
•Switching CRCR on enables LFLF as well.
•Switching CRCR off disables LFLF as well.
•Switching LFLF off disables CRCR as well.
