I have a Supermax mill with fa anuc 18m control.
The machine was in a good working condition. Today I discovered that the Pc attached on its serial port does't boot any more.
After some searching I found that the PC serial port was blown.
From then I cant load or upload anything to or from the machine. I didnt find any other problems except this.
When I try to PUNCH, the control seems to output with no errors and when I try to READ, LSK flashes normany.
Pin 25 of the serial has 24v, Pin2 has about 11v and pin3 about 2v.

Has anyone faced anything similar?
