• If a board released by release_rtc has been the active board, then (other than multi-
board commands) only those non-multi-board commands not requiring explicit access
rights are subsequently available. Another board is not automatically selected as the
active board. Activation of another board (for which access rights are assigned to the
user program) can be achieved by select_rtc.

but release_rtc then has no effect (return value 0).

– CardNo exceeds the number of RTC6 boards found during initialization (see
rtc6_count_cards) and
– No RTC6 Ethernet Board is entered at CardNo
