+Comtrol(tm) RocketPort(R)/RocketModem(TM) Series 
+Device Driver for the Linux Operating System
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+
+PRODUCT OVERVIEW
+----------------
+
+This driver provides a loadable kernel driver for the Comtrol RocketPort
+and RocketModem PCI boards. These boards provide, 2, 4, 8, 16, or 32 
+high-speed serial ports or modems.  This driver supports up to a combination
+of four RocketPort or RocketModems boards in one machine simultaneously.
+This file assumes that you are using the RocketPort driver which is
+integrated into the kernel sources.  
+
+The driver can also be installed as an external module using the usual 
+"make;make install" routine.  This external module driver, obtainable 
+from the Comtrol website listed below, is useful for updating the driver
+or installing it into kernels which do not have the driver configured
+into them.  Installations instructions for the external module
+are in the included README and HW_INSTALL files.
+
+RocketPort ISA and RocketModem II PCI boards are also supported by this
+driver, but must use the external module driver for configuration reasons.  
+

+
+INSTALLATION PROCEDURES
+-----------------------
+
+RocketPort/RocketModem PCI cards require no driver configuration, they are 
+automatically detected and configured.
+
+The RocketPort driver can be installed as a module (recommended) or built 
+into the kernel. This is selected, as for other drivers, through the `make config`
+command from the root of the Linux source tree during the kernel build process. 
+
+The RocketPort/RocketModem serial ports installed by this driver are assigned
+device major number 46, and will be named /dev/ttyRx, where x is the port number 
+starting at zero (ex. /dev/ttyR0, /devttyR1, ...).  If you have multiple cards
+installed in the system, the mapping of port names to serial ports is displayed
+in the system log at /var/log/messages.
+
+If installed as a module, the module must be loaded.  This can be done
+manually by entering "modprobe rocket".  To have the module loaded automatically
+upon system boot, edit the /etc/modules.conf file and add the line
+"alias char-major-46 rocket".
+
+In order to use the ports, their device names (nodes) must be created with mknod.
+This is only required once, the system will retain the names once created.  To 
+create the RocketPort/RocketModem device names, use the command 
+"mknod /dev/ttyRx c 46 x" where x is the port number starting at zero.  For example:
+
+>mknod /dev/ttyR0 c 46 0
+>mknod /dev/ttyR1 c 46 1
+>mknod /dev/ttyR2 c 46 2  
+
+The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes) for you:
+
+>/dev/MAKEDEV ttyR

+REPORTING BUGS
+--------------
+
+For technical support, please provide the following
+information: Driver version, kernel release, distribution of
+kernel, and type of board you are using. Error messages and log
+printouts port configuration details are especially helpful.
