+ The simplest way to configure the serial ports is to copy the provided
+ rc.serial file to the appropriate /etc/rc.d directory.  For example,
+-to install rc.serial on a RedHat system, copy rc.serial to 
+-/etc/rc.d/init.d/serial, and then run the command "chkconfig -add serial".
++to install rc.serial on a Fedora system, copy rc.serial to
