Hi guys, i'm having a hard time establishing a serial connection on a Rj2 system.
I have tried every serial port (p2,p3, p4) and none of them seem yo work.
I dont know if it is a software or hardware related problem, i tried every configuration on the port init, and comm option.
What i would like to know if there is another way to test the serial port, if the cpu need repair, i'll send it out but i want to have some advice from you before send anything out.
Is there a variable in the system that could disable the serial port on the rj2?
The system used to have a devicenet network setup but it is not used anymore, can it be part of my problem?
Thank you guys in advance for your help
