I put an F1364 button on my phone with CM90. I then went to CM9B0 and set 0100 to 0. Is that what you had in mind? It's been the only thing I have been able to find so far to let me know when the connection goes down - at least I hope it does. Of course, we haven't had a problem since I did this, so I don't know yet if it this works the way I'm reading it.

I noticed a posting somewhere where one person was ripping on another's grammar. It's obvious that person never read an NEC manual. That's not a complaint. It's just an observation I find amusing.
