Command (CLOSE)
This command closes a device and switches it into POLL mode. Unless
an addressable command is issued all output is suppressed until a reset
occurs or the OPEN command is used. If serial mode is set to POLL
using SMODE command and the setting is saved to EEPROM (SAVE
command), the device wakes up after a reset still in POLL mode and
output is suppressed also on start-up.
