Yes it works just fine as described.
And Michaelstano thanks so much for going the extra step for a 'list'.
You are right, the RS folks were most helpful. I was not able to get the code loaded with the modem, but no problem with a manual load.
I used a landline but maybe there was excessive noise, etc. but anyway I have it working.
I will pass this info on the folks as remotecentral.com in case they have not caught up yet.
