-/* setserial.c - get/set Linux serial port info - rick sladkey */
-/* modified to do work again and added setting fast serial speeds,
- Michael K. Johnson, johnsonm@stolaf.edu */
-/*
- * Very heavily modified --- almost rewritten from scratch --- to have
- * a more flexible command structure. Now able to set any of the
- * serial-specific options using the TIOCSSERIAL ioctl().
