I hope I used the correct word...

It is a serial bus that is one of the more common, almsost a standard
in the PLC world. Modbus ? I think Modicon released it and called
it modbus.

here, found this....

http://www.modbus.org/

MODBUS® Protocol is a messaging structure developed by Modicon in
1979, used to establish master-slave/client-server communication.

Modbus Protocol becomes IEC Publicly Available Spec: IEC PAS 62030
(pre-standard) The Modbus protocol has been accepted by the IEC as a
Publicly Available Specification (PAS).

And this from ArtSoft's spec page

Full range of G-Code supported.
Polar coordinates, spindle, flood, mist, relays ,
ModBus I/O, Full List of M-Codes.

I'm not sure of the depth of the interface, but sending a serial speed
command to a PIC should be a piece of cake !
