Reply command structure for PJLink commands:
The first 6 bites: the sent command data without change; the 7th bite: "="; after the 8th bite: processing result
For example, if a command, "%1POWR 1CR", is processed normally, the reply command, "%1POWR=OK
CR" will be replied.
PJLink specifications regulate that projectors are required to reply the reply commands within 2 seconds after
receiving the PJLink command. However, some projectors have different specifications. Check the manual of
your projector and apply the response time indicated in the manual if there is one listed.
