How to run mmdvmcal ?

[labdvm]

Hi, I'm using mmdvm repeater with nucleo-446re, two motorola radios, RPi4/2GB and everything works great . I have update the controller with new MMDVM FW, the MMDVMHost works but the latest version of MMDVMCal doesn't work. In previous version of mmdvmcal I used lines:
cd /home/pi/MMDVMCal
./MMDVMCal /dev/ttyACM0
...now this doesn't work !!!
What is new line to open the calibration ?

./MMDVMCal 460800 /dev/ttyACM0
