 command

Hello everyone,

I finally managed to test this patch with our hardware and I'm seeing the same expected behavior as beforehand.

When executing David's test sequence with a EH002004A [1], I'm getting garbled contents when shifting with '\x1b[LR'. But this also happens with the version of the driver we're currently using, does not look related to this patch and might be an issue with our display model.

Best regards,

Christian
