I'm trying to get my Emco 120P ATC to work directly with CSMIO,
the ATC uses 4 signals for 8 tool positions, therefore its easier to read a whole byte of port pins and then mask of the top 4 and then looking for a value as it rotates.
so can I use GetPortByte() which seems to be a mach3 function or do I need to use the Modbus functions such as GetInbit as the CSMIO sample shows ?
