To anybody who can help,

I am posting this question on behalf of my uncle.

My uncle lives near San Luis Obispo, California and has a Macintosh
Plus with the Hayes compatable modem sold by Apple.

His brother lives in Belfast, Northern Ireland and has an Atari ST
with a modem of an unknown type.

They would like to be able to transfer files between their two
computers (apparently there is a "Mac" board that fits in the Atari
and allows Mac software to be run).

This linkup isn't working. It doesn't matter from which direction the
connection is initiated, the symptom is the same. The machine which is
supposed to answer the phone does indeed answer the phone, but the
machine initiating the call never sees carrier detect.

I have heard that American modems and European modems operate by a
different set of rules, but i've never had any personal experience
attempting a telco link from the USA to Europe.

Is this true? Could the problem be that that neither modem will ever
see carrier detect since the other one will never respond in the
required way? If so, does there exist anything like an "international"
modem which can operate according to both sets of rules?
