Notes
When the unit receives the LDEDID command it replies with READY and enters the special EDID
packet wait mode. In this mode the unit can receive only packets and not regular protocol commands.
If the unit does not receive correct packets for 30 seconds or is interrupted for more than 30 seconds
before receiving all packets, it sends timeout error ~nn@LDEDID␠ERR01␍␊ and returns to the
regular protocol mode. If the unit received data that is not a correct packet, it sends the corresponding
error and returns to the regular protocol mode.
See Protocol Packet reference in Section 11.3.1
