I currently have a terminal which I can not get working. It was working then suddenly stopped (according to the user). I have moved the terminal to another location and it works therefore it is not the terminal. I have reset the port (from the DTC Manager) and reset the ldev (from sysdiag). I have gone as far as to redo some of the wiring to the DTC and punched the terminal down to a different ldev and still no luck. My question is: Is there a way to use the DTC Manager Self Test to help determine the cause of this and various other problems? In this situation I have discovered the following: If I do a port loop-back self test it succeeds. If I do a terminal loop-back self test with it wired the way I belief it should be then the self test fails but I get a string of characters on the terminal. If I reverse second pair (which often solves the problem) and perform a terminal loop-back self test I get nothing on the terminal. Any help anyone could give me on this situation would be appreciated.
