Hey All, I'm embarassed to say that the modem problem seems to have been related to my init string not working properly. I used kermit to login manually to my ISP and it all worked??!! So I looked more carefully at my chatscript at noticed that I had been using:
'' ATZL1M1X3 it seems that the extra 'Z' was part of a 'Z0' that got mangled. So the modem was returning 'OK' and continuing without executing the other commands. I don't know why trying the MacOS init string didn't work, though, but since all I wanted was for it to work, I'm now content. Thanks for all your advice, jas.
