problems with SunBlade 1500

I have a bunch of different Sun systems connected to my 16 port CMs, and have no problems with anything except for Sun Blade 1500 (workstations being used as servers.) Specifically, when I open a connection to the port, I often, but not allways, get junk characters, and any input from my keyboard seems to send a break sequence. Only recovery has been with a hard reboot at that point. I have tried the 9 pin digicm console adapter with both a flat cable and the sun/cisco cable, as well as wiring my own cables up using the pinouts in the rear of the manual. Has anyone else run into this problem?

You should NEVER get a break! Outside of old CM firmware, I have not heard of this problem. Does this happen on multiple CM’s? What version of CM firmware are you running?
