Here's a confusing one, I unplugged my console, it booted up ok, however I get a blinking cursor. I can go into setup and look at the terminal configuration, and even when I type it is being sent out to the printer, meaning I can even log into the pbx, but for some reason what I'm typing is not showing up on the montior, but is actually working as it is showing on the printout. So the keyboard works, any thoughts?
