This is a X-post from the AVR forum as I wasn't sure where to go wtih this question...

Hi all,

I've been experimenting with controlling a Yamaha AVR and a Sound Projector with RS232. It seems that these devices are only able to accept commands at fairly wide intervals. If I send repeated commands to ramp volume it takes a long time for all the commands to be processed.

Has anyone else seen this? Does anyone know a way around this? Is there a configuration option to speed things up?

I appreciate any help you can give.

Regards,

Phil
