Hi Alfred.
Several of the developers spent time trying to figure out a way to convert the second parport configuration options from EMC to EMC2. If memory serves this was the only recommendation of the Fest at NIST that was not able to be implemented. I'm not at home right now so can't test and send a sample hal file. The steps to setting one up working from stepper inch are like this. In the standard_pinout.hal file you need to add the parport and connect its functions to threads. The existing file looks like this. # first load the parport driver loadrt hal_parport cfg="0x0378" # # next connect the parport functions to threads # read inputs first addf parport.0.read base-thread 1 # write outputs last addf parport.0.write base-thread -1 # The hal manual suggests the following sort of expansion of the single parport load command. loadrt hal_parport cfg="0x278 0x378 in 0x20A0 out" Since the command defaults to out and that was the way the old second parport worked you can simply insert the two addresses between "". Now you need to add the second parport to the appropriate threads. You could just copy the existing addf lines and change to parport.1.xxx. If you are being time conscious you could add the second parport's functions to the servo thread rather than the base. With these changes you will see the second parport when you start up the configuration and look at it with halshow or halcmd. From there you should be able to figure out how to connect the extra pins to the signals you want to use them for. Good luck.
