1. A mortise lockset, comprising:
a mortise case;
a latchbolt mounted in the mortise case for movement between an extended position and a retracted position;
a hub rotatably mounted in the mortise case for movement between a home position and a rotated position;
a retractor configured to retract the latchbolt in response to rotation of the hub from the home position to the rotated position;
a holdback having a hold position and a release position, wherein the holdback in the hold position is operable to retain the latchbolt in the retracted position, and wherein the holdback in the release position is inoperable to retain the latchbolt in the retracted position;
an electronic actuator engaged with the holdback, wherein the electronic actuator is configured to drive the holdback from the release position to the hold position in response to an unlocking command, and wherein the electronic actuator is configured to drive the holdback from the hold position to the release position in response to a locking command; and
control circuitry configured to perform an unlocking operation in response to an unlocking signal, and to perform a locking operation in response to a locking signal;
wherein the unlocking operation comprises transmitting to the electronic actuator the unlocking signal, thereby causing the electronic actuator to move the holdback from the release position to the hold position; and
wherein the locking operation comprises transmitting to the electronic actuator the locking signal, thereby causing the electronic actuator to move the holdback from the hold position to the release position.
