if the modem is internal, it may very well shut down... an external one, on the
other hand, may not... it depends on how it is configured with the serial
control lines and what happens to them when the software or system goes down...
this is one of the reasons why i always use external modems and not internal
ones... externals i can just turn off and rest but internals have to have the
machine rebooted and maybe even hard rebooted or powered off instead of just a
soft boot...
