I'm not showing errors on the 384i system. The programming looks right. I can plug my laptop in to the 3dci and get a response back. I can do the same with the nvm, in link mode to get characters on the screen on the nvm. I've reset the vm and ps.

Also no link light on the 3dci

I also tried reinit the dci ports

Have you tested the cable?

I used that cable to get a response back from the 3dci. So I think it is good.

Maybe LAPB CCA? Is there a way to rule that out?

Ya, but did you use a null modem or does it need to be straight through?

I'm not sure if it was straight through or null. However I used the old cable that went from the 3dci to the vm, to connect the 3dci to my laptop. I sent AT command, and received back a response.

PMS software for the 384i system itself? Is this different than the regular software disk? If not, where is this software located?

Changing LAPBU cca didn't help. Is there a hotel license located in the system?

Yes,
the system has a dongle or a patch to allow PMS and Hotel integration.

email me if you still need assistance.
