A serial link, with JMRI thinking its talking to a C/MRI system and your hardware-control PC emulating a C/MRI system, will work for Turnouts and Sensor.
But it won¡¯t work for throttle control from JMRI. C/MRI, hence the C/MRI protocol, doesn¡¯t know how to do that.
So you can either use a 2nd serial link from JMRI to the EasyDCC system directly, bypassing your PC, or you can use a 2nd serial link from JMRI to your PC that¡¯s carrying the EasyDCC protocol.

Thanks, Bob. I'm a little closer to understanding. All of your reply was clear, until the final question about two serial links to the PC. Does C/MRI always and only use a serial link to the computer? Or, where else were you envisioning it? I didn't expect to duplicate C/MRI interface hardware, only mimic enough to use the same message structures.
It seems I should research C/MRI before asking anyone on this list to answer questions about connecting JMRI to it with my hardware.
