Here is a collection of info I have picked up. I am quoting several
messages that have been sent to me in an exchange on the subject, and it
may, or may not interest you, but it's basically everything I could find
out, and it gives you the alternative of possibly using an off the shelf
modem. Depends on you application and finances.

Many 56k modems sold in Oz and no doubt NZ support caller ID. Just use a
terminal program to issue the command 'AT#CID=1' - this enables caller
ID info to be sent in the normal 'RING' message from the modem. Give it
a call and watch!

One user told me he has a Netcomm 56k unit - AM3477 - and it works well.
The feature is not documented in the manual, though. It also works well
with the latest versions of 'Winfax Pro'. When a call is received, the
CLI is shown in Winfax's receive log.

You may not even need to write any database software, unless it is for a
very specific application. There are quite a number of programs
available already. Here are some caller ID programs at winfiles.com in
the misc. telephony section.........

There are many more to be found if one searches the net.

Also, before you buy a 56k modem, check that it supports the CLI
feature. Usually, it won't be in the manual (just like all of the fax
specific AT commands never are), so it's best to test the feature (or
get a friend to do it on their modem).

Also see this FAQ for lots more details. UK biased, but most of the
principles are the same, and the software works everywhere more or less.

Caller ID units:
The EM924547 is in both the OMNI CA290 and the Uniden Caller ID unit
that are available in OZ. It is the FSK CLI decoder. The Data pin is the
same as the Motorola MC145447.

Now if any of this helps you to get the 84 going as a caller ID monitor
great. It's all the info I have.
There are two caller ID units on the market in kit form. These are to US
standards however. One was from ITU Technologies (sadly, no longer
available), and the other I seem to have lost the link, but I'm sure a
search will pick it up.

an a serial LCD?
