AX2850 Analog mode Estop reset

In serial mode, you can clear an Estop by issuing a reset command. However, if an Emergency stop is received while the controller is in Analog controller input mode, you cannot switch to serial mode (by sending 10 cr) and then issue a reset command. If an Emergency stop is set while in analog mode, the only option is to power cycle or push the reset button.
It would be nice if, after an Emergency stop in Analog control mode, the controller could still be switched to serial control mode.
