PID SERVO TUNING

I don't think that it is very common, but neither is it anything to avoid or worry about.

It also says "VT52" and there are lots of ways to emulate that with modern hardware, including using the LinuxCNC PC assuming it has a serial port.
See, for example, the discussion here: unix.stackexchange.com/questions/22545/h...-simple-as-using-ssh

I have used "screen" on my Mac to monitor the low-level BIOS output of a single-chip computer. It definitely ought to work.

if the drivers lost the tuning settings is there some led indication to point that?

Hi
i try to auto tune the motors and the drivers via serial communication
i install minicom to establish communication threw linux pc and the driver
when i enable the driver the minicom terminal saw the correct message in the terminal screen but ether the escape or th P key are not working any suggestions?
