I have a phone line with call waiting that doubles as my modem line. The problem is when a call comes in on the wait line while I am on-line to where ever, I get my line dropped and then the phone rings through with the wait line call. I am using a EMP 1200E modem (darn cheap and Hayes compat.) and Procomm 2.4.2 what can I do to stop this nasty business of being kicked off all the time. I would like to know the call on the wait line is coming in and then *_I_* could decide what to do about it etc...... Any ideas or solution. It would be much appreciated (MUCH).

It would be much appreciated (MUCH). Set your dialing prefix to *70 (touch-tone) or 1170 (pulse dial) in ProComm. This turns off call waiting for the duration of the current call. Be forewarned that not all exchanges let you do this, but it works here, and the worst that can happen to you is you'll get a recording saying you've misdialed. Of course, call waiting is an abomination the world would be better off without, but that's a different matter! :-) ==Jess Anderson===Academic Computing Center=====Univ.

There is a public domain program called CW which is used to disable call
waiting. Send me mail and I will send you a version of this program...

It would be much appreciated (MUCH). Depending on the equipment that your local telephone company is using, you may be able to shut off call waiting. But this would work on outgoing calls only. An AT&T switch uses *70 to turn off call waiting for the next outgoing call (1170 if you have pulse/dial service). You may be able to redefine the amount of time that your modem will accept loss of carrier and not hang up. I remember seeing this in my modem documentation, but I don't have details right at hand. It does not seem likely that you will be able to receive a signal that a new call is in (call waiting is diabled or the modem will simply ignore the call waiting signal).

Try your local phone company. Some of them offer a service that allows you to turn off call waiting by dialing a special sequence. This posting reminds me of a guy I work with. At a previous job he only had one modem on his computer. The only people who called the number were Paul and his co-worker. Fortunately for Paul, the co-worker had call waiting. Whenever the modem was busy, all Paul did was call the other guys phone which immediately knocked him off the line and freed up the modem. :-) I don't think the other guy ever knew what was happening to him. -- ____________________________________________________________________________ Rick Kimball | Mac Source BBS, Altamonte Springs, FL DATA (407) 862-6214 | VOICE (407) 788-6875 UUCP: rick@kimbal ..!gatech!fabscal!kimbal!rick ..!ucf-cs!sdgsun!kimbal!rick

I think your best bet is to disable it. In the Dec 26, 1998/Jan 2, 1989 issue of PC WEEK mag Jim Seymour's column, "The Corporate Micro" (page 69), discusses a pricey gadget from Rainier Technologies in Redmond, Wash. ($395) that he claims solves the problem. He calls it a voice-data switch and you can hear a demo by calling Rainier Technologies at: (206) 881-5304.

It's the one that tells the modem how long a carrier loss should be before it will disconnect. When the call-waiting signal comes in and the ATS7 is set high enough, the modem will just wait out the amount of time specified and hopefully by then the carrier will be back. You'll get some garbage on both ends of the line but it's better than being disconnected. -- --- herb@blender.UUCP "Did I tell you I'm forgetful?"

Callwaiting is signalled by *interrupting* your connection and sending
the "beep". This means that *any* modem will see that signal as loss of
carrier. And thus the connection goes away...
Even if you set *your* modem to wait longer than normal before doing a
disconnect when it loses carrier, how do you insure that the *other*
modem won't hang up when *it* sees the loss of carrier?
Call waiting and modems do *not* mix! If you are using this line only
for *outgoing* calls AND your phone company offers it, get "call
waiting disable". This allows you to turn off call waiting for the
duration of the *current* call by dialing a code before dialing the
number (usually *70 or 1170, but other codes are used!) When you hang
up, call waiting will once again be in effect.
If you have this option, then just change you dialing commands:
ATDT555-1212
becomes
ATDT*70,555-1212
Or just cancel the (dis)service....

On the Smartmodem 2400 it defaults to 14 (AT S10=14); setting it higher (e.g. S10=50) will cause call-waiting to garble your line but not hang up. ++Brandon -- Brandon S.

this is a summary of responses. I received many (many!) responses (all by mail, Thanks to all who mailed.) but they fell into a limited number of responses. Summarizing the most important one, most phone services with call waiting feature have a temperary defeat mode accessed in my area code (519) by first entering *70 then going on to dial your number. The defeat lasted the length of the call. Most area codes will have a simillar feature as will most local phone companies. For Procomm specific users you just add *70 to the dial string, then two commas and the the number to dial. This gives a delay for the phone to complete the defeat operation. There you have it. Thanks again to all. Good luck to you and your modem :-) -Robert H.
