dial a pager

Hello group-
I have a need to have a Basic stamp monitor a circuit and activate a
phone dialer that has the capability to send a numeric string so that
a pager will know who called. Does anyone have any ideas on a dialer
that would have that capability? The Radio Shack dialer only gives a
audio message, so it is not suitable. Is there a way to utilize the
DTMF function of the Stamp to do this? Any helpful ideas will be
greatly appreciated.

    You can use any off-the-shelf modem to dial a paging service and put a
    numeric message on a pager. The key is keeping the modem in command state by
    adding a semicolon to the end of the string that dials the number. Then wait
    for the service to be ready and send the numeric message. It's very simple.

    Parallax carries the Cermetek CH1786 modem that is great for embedding in
    projects like this (take a look at www.hotwireftx.com -- uses a BS2 and
    Cermetek modem). There is a file on the Parallax web site that has the code
    and data from my "Stamp Applications" column in the April issue of Nuts &
    Volts magazine. I think you'll find it helpful.

    if you have a netpliance I-opener(www.netpliance.com), there is a TTL
    serial modem inside.
    I hacked my I-opener to run linux and put a network adapter in it, so
    i just took out the modem card (which is about the size of a pack of
    cigarers)
    to make room for a hard disk. ... should be easy to directly interface to a
    stamp.
