   You can use DosDevIOCtl to change the timeouts as long as you have an
   open handle to the COM device.  In the case of your "shim", you would
   have to set up your mailer to spawn your program in such a way that it
   inherits the open file handle.  All halfway decent OS/2 mailers, such
   as BinkleyTerm, allow you to spawn programs, and pass the number of the
   open file handle to the COM device that will be inherited as a
   parameter on the command line.

   You can then use DosDevIOCtl on that file handle to make adjustments to
   timeout and suchlike, and in turn spawn the BBS program.
