if you have 4 or less axes/modes to choose from, you could encode the position of a rotary switch into 2 bits. That way you save a bit of I/O. Saving would be even more with an 8-position switch, which can be represented with 3 bits. For jogging, it is best to connect the jogwheel count directly to emc's motioncontroller, as in my example: http://www.anderswallin.net/wp-content/2006_11jog/jog.hal you see that the jogwheel count is wired to axis.X.jog-counts this is a connection directly to emc's motioncontroller, and does not require halui. I think people tried physical jogwheels through halui and found that jogging was jerky, that's why jog-counts pins were added to the motioncontroller.
