Message 8 - Flamingo Emulation
For compatibility in the system level, LT31 also supports the message

accepted only when the FLAMINGO message emulation is selected. The
FLAMINGO emulation mode is selected with the SET MESSAGE

The FLAMINGO polling format is as follows:
"H0C!S0P_ _ _ _ _ _ _ _ _ _0B$
