Hello Terry,

Any more info on the DSC alarm?  I went to a local supplier to look at
one.  I notice they have a connection for phone interface but I didn't 
see anything for serial interface.  How are you doing this?  Thanks for
the info.

The analyzer is coming from my work, on a dedicated Compaq "portable".
Old but reliable, it gets the job done.

I'm getting my equipment from Baran-Harper, but there's several good
suppliers on the net with what I thought was good pricing, as low as
$140 for the alarm panel and led keypad (8 zone).  The intercom units
are a tad biiger than a dollar bill standing vertically, with two
buttons. Very clean lines.

I expect to get the unit by Saturday and I'll post what I find about
the
protocol it uses.
