Hello Roger!
Replying to a message of Roger Nelson to Kathleen Weaver:
 RN> As far as I know, all 28.8 and I assume  33.6 modems have CID
 RN> built-in.  It could be that you entered the command incorrectly,
 RN> which is so often easy to do.  Just make sure that it is like this:
 RN> AT#CID=? and press Enter.  On most modems the syntax is
 RN> case-insensitive, but since I don't own a USR modem, I can't speak to
 RN> that.
Yes, I didn't that.  And none recognize that command.
 RN> If you did enter the command correctly and received the dreaded
 RN> "ERROR" response from your modem, then it doesn't support CID.
Yes, that's what I got.
