I got called out to a place that has a DSUII (gray) L1632. I believe this is just a DSUII also, but normally they are black. I'm a little rusty on this one since I was probably in high school when this thing was made.

I checked program 15 and the ports are definitely set at 9600-8-1. I am unable to get my laptop to connect to any of the ports... Com 1-4. I tried restarting he phone system just in case a port was locked up. I think that I've connected to this in the past, but I'm not 100% positive. Would it be likely for all four ports to have something wrong with them? I tried my laptop serial port and also and usb to serial and cannot get any response with hyperterminal or putty.

Any suggestions?
