I have a OfficeServ 100 (aka iDCS100 R2) which i was in the process of upgrading to 2.69, however before i could upload the new SP file, the system was turned off, and hence won't boot.

Now i have a recovery procedure where you connect a serial cable to certain pins on the mcp and hold enter while the system boots, but while doing that it doesn't work, i can see all the startup stuff, but i don't get the password prompt.
I have done this once before on 2.63 and i got to the prompt, but this one won't do it.

Any suggestions?
