Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

6 | PRODUCT OVERVIEW | ||
7 | ---------------- | ||
8 | |||
9 | This driver provides a loadable kernel driver for the Comtrol RocketPort | ||
10 | and RocketModem PCI boards. These boards provide, 2, 4, 8, 16, or 32 | ||
11 | high-speed serial ports or modems. This driver supports up to a combination | ||
12 | of four RocketPort or RocketModems boards in one machine simultaneously. | ||
13 | This file assumes that you are using the RocketPort driver which is | ||
14 | integrated into the kernel sources. | ||
15 | |||
16 | The driver can also be installed as an external module using the usual | ||
17 | "make;make install" routine. This external module driver, obtainable | ||
18 | from the Comtrol website listed below, is useful for updating the driver | ||
19 | or installing it into kernels which do not have the driver configured | ||
20 | into them. Installations instructions for the external module | ||
21 | are in the included README and HW_INSTALL files. | ||
22 | |||
23 | RocketPort ISA and RocketModem II PCI boards currently are only supported by | ||
24 | this driver in module form. | ||
25 | |||
26 | The RocketPort ISA board requires I/O ports to be configured by the DIP | ||
27 | switches on the board. See the section "ISA Rocketport Boards" below for | ||
28 | information on how to set the DIP switches. | ||
29 | |||
30 | You pass the I/O port to the driver using the following module parameters: | ||
31 | |||
32 | board1 : I/O port for the first ISA board | ||
33 | board2 : I/O port for the second ISA board | ||
34 | board3 : I/O port for the third ISA board | ||
35 | board4 : I/O port for the fourth ISA board | ||
36 | |||
37 | There is a set of utilities and scripts provided with the external driver | ||
38 | ( downloadable from http://www.comtrol.com ) that ease the configuration and | ||
39 | setup of the ISA cards. | ||
40 | |||
41 | The RocketModem II PCI boards require firmware to be loaded into the card | ||
42 | before it will function. The driver has only been tested as a module for this | ||
43 | board. | ||
44 | |||

47 | INSTALLATION PROCEDURES | ||
48 | ----------------------- | ||
49 | |||
50 | RocketPort/RocketModem PCI cards require no driver configuration, they are | ||
51 | automatically detected and configured. | ||
52 | |||
53 | The RocketPort driver can be installed as a module (recommended) or built | ||
54 | into the kernel. This is selected, as for other drivers, through the `make config` | ||
55 | command from the root of the Linux source tree during the kernel build process. | ||
56 | |||
57 | The RocketPort/RocketModem serial ports installed by this driver are assigned | ||
58 | device major number 46, and will be named /dev/ttyRx, where x is the port number | ||
59 | starting at zero (ex. /dev/ttyR0, /devttyR1, ...). If you have multiple cards | ||
60 | installed in the system, the mapping of port names to serial ports is displayed | ||
61 | in the system log at /var/log/messages. | ||
62 | |||
63 | If installed as a module, the module must be loaded. This can be done | ||
64 | manually by entering "modprobe rocket". To have the module loaded automatically | ||
65 | upon system boot, edit the /etc/modprobe.conf file and add the line | ||
66 | "alias char-major-46 rocket". | ||
67 | |||
68 | In order to use the ports, their device names (nodes) must be created with mknod. | ||
69 | This is only required once, the system will retain the names once created. To | ||
70 | create the RocketPort/RocketModem device names, use the command | ||
71 | "mknod /dev/ttyRx c 46 x" where x is the port number starting at zero. For example: | ||
72 | |||
73 | >mknod /dev/ttyR0 c 46 0 | ||
74 | >mknod /dev/ttyR1 c 46 1 | ||
75 | >mknod /dev/ttyR2 c 46 2 | ||
76 | |||
77 | The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes) | ||
78 | for you: | ||
79 | |||
80 | >/dev/MAKEDEV ttyR | ||
81 | |||

84 | ISA Rocketport Boards | ||
85 | --------------------- | ||
86 | |||
87 | You must assign and configure the I/O addresses used by the ISA Rocketport | ||
88 | card before installing and using it. This is done by setting a set of DIP | ||
89 | switches on the Rocketport board. | ||
90 | |||
91 | |||
92 | SETTING THE I/O ADDRESS | ||
93 | ----------------------- | ||
94 | |||
95 | Before installing RocketPort(R) or RocketPort RA boards, you must find | ||
96 | a range of I/O addresses for it to use. The first RocketPort card | ||
97 | requires a 68-byte contiguous block of I/O addresses, starting at one | ||
98 | of the following: 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h, | ||
99 | 0x300h, 0x340h, 0x380h. This I/O address must be reflected in the DIP | ||
100 | switiches of *all* of the Rocketport cards. | ||
101 | |||
102 | The second, third, and fourth RocketPort cards require a 64-byte | ||
103 | contiguous block of I/O addresses, starting at one of the following | ||
104 | I/O addresses: 0x100h, 0x140h, 0x180h, 0x1C0h, 0x200h, 0x240h, 0x280h, | ||
105 | 0x2C0h, 0x300h, 0x340h, 0x380h, 0x3C0h. The I/O address used by the | ||
106 | second, third, and fourth Rocketport cards (if present) are set via | ||
107 | software control. The DIP switch settings for the I/O address must be | ||
108 | set to the value of the first Rocketport cards. | ||
109 | |||
110 | In order to destinguish each of the card from the others, each card | ||
111 | must have a unique board ID set on the dip switches. The first | ||
112 | Rocketport board must be set with the DIP switches corresponding to | ||
113 | the first board, the second board must be set with the DIP switches | ||
114 | corresponding to the second board, etc. IMPORTANT: The board ID is | ||
115 | the only place where the DIP switch settings should differ between the | ||
116 | various Rocketport boards in a system. | ||
117 | |||
118 | The I/O address range used by any of the RocketPort cards must not | ||
119 | conflict with any other cards in the system, including other | ||
120 | RocketPort cards. Below, you will find a list of commonly used I/O | ||
121 | address ranges which may be in use by other devices in your system. | ||
122 | On a Linux system, "cat /proc/ioports" will also be helpful in | ||
123 | identifying what I/O addresses are being used by devics on your | ||
124 | system. | ||
125 | |||
126 | Remember, the FIRST RocketPort uses 68 I/O addresses. So, if you set it | ||
127 | for 0x100, it will occupy 0x100 to 0x143. This would mean that you | ||
128 | CAN NOT set the second, third or fourth board for address 0x140 since | ||
129 | the first 4 bytes of that range are used by the first board. You would | ||
130 | need to set the second, third, or fourth board to one of the next available | ||
131 | blocks such as 0x180. | ||
