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....
