There is only a pause (or "guard time") on Hayes modems or modems from makers that have a Hayes "guard time" license. Hayes patented the idea of a guard time, and many modem makers simply dropped the guard time rather than pay Hayes.
See the BUGTRAQ mailing list (about a month ago) for an in depth discussion of this and how it can be a problem. -- Chris Adams - cadams@ro.com System Administrator - Renaissance Internet Services I don't speak for anybody but myself - that's enough trouble.
