Script commands to control PlanetCNC

Hello,

I´m doing a VB program to control a PlanetCNC software.
With a DOS command (under Win10) already works the load of PlanetCNC ("CNCUSBController.exe"), load of Gcode and start of machine ("CNCUSBController.exe -mdi/401").

Now I need to follow the progress of machinery. I think read the "line count command" and "line command" ("CNCUSBController.exe linecount" and "CNCUSBController.exe line"). I don't have any error but also I don't see any value. Were this (and others) values are returned?

Also I think use the log file but I don't know were it is saved. Can somebody help me? Regards.

How to control PlanetCNC TNG from your own software tutorial:

For advanced interprocess communication you would need to use "named pipes". A list of supported commands is available in the link provided.

Thanks. I know that page. My question is were the return values appear, were we can see them.

I want to say "where"! (At cmd display don't appear nothing)
