/* This program sends a file out the serial port to the PDP8.  Use for
   sending paper tape images.
   It will prompt for the file to send or use first command
   line argument.  It needs a config file dumprest.cfg or $HOME/.dumprest.cfg
   with the format defined in config.c

   The PDP8 end should be running before this program is started

   On the PC ctrl-break will terminate the program
