Pacific Bell in California uses *70 to cancel call waiting for the duration of the following call. There is a pulse equivalent but I don't know what it is and it's not explained in the phone book. Another way around loosing your connection is to set the LOST CARRIER TO HANGUP DELAY at 2 sec. This may be changed depending the duration of the BEEP tone you hear when another call in coming in. Since the long BEEP is only on your receive line, your modem should be the only one needing this change. The remote end just hears a CLICK. This click is short enough not to affect the remote modem. Obviously all modems can't be programmed for this delay. On Hayes (and most compatibles) the register S10 is where you want to diddle. Some compatibles use a default and only have the register there for compatibility. When in doubt, try a Hayes -- I know it works like I described. I hope this helps. Scott O'Connell - Datagram Corp.

Talking about callwaiting dumping modems, beacuse they interpret the boop to be a break...

Is there a way to avoid being dumped at 1200 ? (As far as I am aware, our phone company doesn't offer dis- abling call waiting.) Do *real* hayes use this value at any speed ? Even 2400? -- Dragos Ruiu Disclaimer: My opinons are my employer's, I'm unemployed!

This looks like no-carrier to the far-end modem. The duration of the silence will be the duration of your beep, plus a little. This means that in some cases, re-programming your modem to ignore a short carrier-outage won't help you unless the far-end modem is similarly re-programmed. The *70 option is probably a better way, if it's available. -- Dave Levenson Westmark, Inc. A node for news. Warren, NJ USA {rutgers | clyde | mtune | ihnp4}!westmark!dave
