     According to the manual for my USR HST Dual Standard, using the
"Fast Dials" feature is not the same as setting S6 to zero.  Fast
Dials causes the modem to wait for a dial tone and then dial
immediately.  Although S6 *can* be set to zero, my local exchange will
not accept the whole number unless the modem waits at least one second
or uses Fast Dials.

     Fast Dials is part of the Adaptive Dialing feature, where the
modem monitors the response to its dial attempt.  In addition to Fast
Dials, the HST will first attempt to tone dial, and then revert to
pulse if dial tone is not broken.

     Pretty neat, eh?
