Hello, everyone!

Have been working with my Fadal for about half a year right now and today I stumbled across problem that I just can't figure out. Long story short I am sending my programs to CNC via RS232 cable, Cimco program on my PC. Suddenly today CNC is not responding to my actions on computer - type TA (or TA,1, doesn't matter) on CNC, press Enter. CNC is waiting for a program to receive. Then I am pressing "SEND" in my Cimco software and everything looks fine right there. It shows that program is sent like it normally does. But in reality nothing happens on CNC, it still shows TA, waiting for a program to be sent.

Went through all my COM port, Cimco, CNC, Baud rate etc. settings and everything is correct like it was for this half year. Cable wiring looks good to me just like before.

What could be the problem and do you have any suggestions? Could it be CNC hardware?

Thanks in advance, hoping for help asap.
