[Hai-users] X10 quit working

[Jack & Lynda Carnegie]

I have an Omni IIe (the one with 3 serial ports).  All my x10 has stopped working. If I connect to the controller with pc access and tell it to send a command the red light on the tw523 interface does not blink.  There are two red lights on the controller board next to the Ethernet and x10 ports. The left one is constantly red, the right one is blinking. I am not sure what these lights signify.  I am not sure if the tw523 went bad or the x10 output on the controller board stopped working.
Can anyone help troubleshoot. Fwiw, UPB works fine.
