I need learned codes for various type of remotes, except SONY, because for
the
SONY remotes is now clear for me, with a great help from a list member,
Keith Smith.
Thank you Keith.

Not really like that. Just try my application . select the right COM
port
then click on Autodetect.
It must initialize as IRMan and display a confirmation message. Then
try to
record some commands.
IRMan support is implemented for record only, but the reason I ask
for help
is to try to implement
a compatible send function for the IRMAn captioned commands.

More than that. It is the binary representation of the transmitted
code. I
have checked it for
Sony and it is 100% correct, even if the rest of the bits (till 48)
are all
'0's.

I know... the initialization routine is implemented in my
application
starting with the version 1.4.x. Just check it.
