| 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/modprobe.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 |
