I just shorted pins 3-4 on a RJ-11 keystone jack. Plugged in and tested with hyperterminal and I could see what I was typing. All the local echo settings are off. So, I'd say the issue was that DSUII. The stuff in my old timey laptop bag doesn't get used often, but I do believe it's all good. If I ever go back there I'll try again, but I'm thinking something is toast on the DSUII. I ended up using the block programming feature to copy the stations from the attendant extension.
