CPEDID
Copy EDID data from
the output to the input
EEPROM.
Destination bitmap
size depends on
device properties (for
64 inputs it is a 64-bit
word).
Example: bitmap
0x0013 means inputs
1,2 and 5 are loaded
with the new EDID.
In certain products
Safe_mode is an
optional parameter.
See the HELP
command for its
availability.
