Hook-up with 3M sensitivity solutions so that when you checkout an item in Koha it sends a code (LL) to the 3M system to switch it to Sensitize OFF, and when you checkin an item in Koha it sends a code (RR) to switch the 3M hardware to Sensitize ON. Note : some other sensitivity tools seems underway. Need some clarification !
Is there a patch available for testing?
