then write a hal module modbus.c: #include rtai_serial.h #include hal.h ... // use rt_spopen(), rt_spwrite, rt_spread and friends you'll need to implement the modbus protocol in your modbus.c module and expose some hal pins for the emc Z axis logic it is not hard to do but remember: once you're done please post it (the modbus driver) to this list ;) ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
