Hello Nick...

Because the modem may not be configured to drop carrier and hang up.  Any
modem configured properly should, but there is no
guarantee.  If the modem doesn't have &D1 in the init
string, in memory, or set by default, dropping DTR may not
cause the modem to hang up.  But it's safe to assume that
it will if we're talking modern, standard, IBM PC modems
running recent software.
