The `Organization' line in your header seems to indicate that you are in Germany. According to my phone book a busy signal in Germany is `short, sharp tone repeated at frequent intervals' while the busy signal in the US is `tone off and on for equal periods no longer than 1 second'. It seems likely that the modem is listening for US busy tone, so it dosen't recognise your busy tone. You could confirm this by dialling a number in the US which you know is busy (perhaps some US reader knows a telco test number??). Interestingly enough, every one of the six signals listed in my phone book is used for both `ringing' and `busy' in different countries. e.g. the US busy tone is the ringing tone in Denmark, and the German busy tone is the ringing tone in the Solomon Islands. Have any readers ever tried to call the Solomon Islands (especially with a modem) who could confim this? -- Charles Bryant (ch@dce.ie) -- If you like the opinions expressed in this message, they may be available for rent - contact your local sales office.
