Nvpswd -- Change Non-Volatile Memory Password - Polycom Vortex EF2211 Programming Manual

This command is saved to global non-volatile memory and is not part of a preset. Its value is saved
each time it is changed. It will retain its value after power-down. Since this command writes to non-
volatile memory, there will be a delay before an acknowledgment is returned.
