Thanks for the responses - as it happens it was more down to me not entering the modem stat specification correctly into the terminal program. Once I got something accepted then I heard the 'ping' of the relay to switch in the modem circuit and was able to hear the familiar screeching via the acoustic coupler.
I haven't got anything to work reliably however which is a shame but it was a long stretch. I bought a 'retro' bluetooth handset and paired it with my mobile phone. There may be still some mileage in it but I suspect there are too many compression algorithms in the way. I may need to resort to a direct connection cable or external modem instead. Mark.
