Beside this port on NUM 1040 there is second port Com 1 in my case using for Handwheel which manage axes manually when it is needed. The Com 1 works properly and no problem at all. Serial and Com 1 are near each other on NUM and it is funny that one serial port working another not... I have checked everything regarding setup PC and machine, configuration both PC and CNC but result is zero!
Before that with the same port setup (Serial) PC and CNC machine worked as mentioned great...
I will very thank you anyone can help with my readiness to compensate for an expert help!
Regards!
