For modems that use the serial wave device, the StopPlay command is made after AbortPlay or TerminatePlay. This command can be used to reset the modem's baud rate, if it was changed for playing. For modems that use the wave wrapper wave device, this command is called after StartPlay, and should issue all necessary modem commands to stop playing the wave file.
