I had a heck of a time trying to program the MX-3000 with the virtual key codes supported by the Crystalio II so I thought I'd post the 'rcc' file in the hopes that others might find it useful. It's not pretty, in fact it's fairly basic, but it does have all 20 virtual keys. Enjoy!!!

Are those created from the CCF file that PixelMagic provides?

Close, the ccf that Pixel Magic provides wasn't compatible with my Pronto, it's an old model, don't really use it anymore except it was the only way to have my MX-3000 learn the virtual keys. Anyhow, I obtained the raw hex codes for the Pronto from the Pixel Magic forum. I cut and pasted them into the Pronto and used the Pronto to program the MX-3000. I verified that all the virtual keys worked.

Gotcha. It's cool that you decided to share your hard work with the community.

It also sounds like you'd be a perfect candidate for URC's MSC-400 to get RS232 control
