   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...
