I am using a Hayes compatible modem in my PC. Everything works fine, except that the modem does not recognize when the number it dialed is busy. Instead it waits for some time and then says: NO CARRIER. Is there some setup option I missed, or what is the reason for this behaviour? Any hints will be appreciated. Thanks, Kai.

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.

Most 2400 bps modems (and a few 1200s from Prometheus and others) have BUSY detect capability, but you must first enable X level 4 (or higher).

Try setting your Response Messages to ATX3 or greater. If you are
at ATX0,1,or 2 you will not get the BUSY response.

Neither you nor your modem is stupid but the German Bundespost Telecom is! They simply don't send the right busy signal! Your modem will recognize US busy signals but no german ones. -- ------------------------------------------------------- Klaus Hartnegg, Kleist-Str. 7, D-7835 Teningen, Germany Bitnet : HAKL@DFRRUF1 or HARTNEGG@CERNVM Internet : HAKL@ibm.ruf.uni-freiburg.de

With my modem I can get the BUSY and other responses if I set the command responses to X3 or X4 (type ATX3 or ATX4). Try and see if your modem is able to understand this. According to my manual you get: CONNECT, NO CARRIER and ERROR with X0 CONNECT (speed), NO CARRIER and ERROR with X1 CONNECT (speed), NO CARRIER, ERROR, BUSY, NO ANSWER with X3 or X4 X2 means: Same as X1, but the modem waits for a dial tone before dialing.

If your modem is capable of "ATX4" that will solve your problem, otherwise bad luck....use your good ear!
