Linux-2.6.12-rc2v2.6.12-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!

| 16 | ----------------------------------------------------------------------------- | ||
| 17 | 1. Introduction | ||
| 18 | |||
| 19 | The Smartio family Linux driver, Ver. 1.1, supports following multiport | ||
| 20 | boards. | ||
| 21 | |||
| 22 | -C104P/H/HS, C104H/PCI, C104HS/PCI, CI-104J 4 port multiport board. | ||
| 23 | -C168P/H/HS, C168H/PCI 8 port multiport board. | ||
| 24 | |||
| 25 | This driver has been modified a little and cleaned up from the Moxa | ||
| 26 | contributed driver code and merged into Linux 2.2.14pre. In particular | ||
| 27 | official major/minor numbers have been assigned which are different to | ||
| 28 | those the original Moxa supplied driver used. | ||
| 29 | |||
| 30 | This driver and installation procedure have been developed upon Linux Kernel | ||
| 31 | 2.2.5 and backward compatible to 2.0.3x. This driver supports Intel x86 and | ||
| 32 | Alpha hardware platform. In order to maintain compatibility, this version | ||
| 33 | has also been properly tested with RedHat, OpenLinux, TurboLinux and | ||
| 34 | S.u.S.E Linux. However, if compatibility problem occurs, please contact | ||
| 35 | Moxa at support@moxa.com.tw. | ||
| 36 | |||
| 37 | In addition to device driver, useful utilities are also provided in this | ||
| 38 | version. They are | ||
| 39 | - msdiag Diagnostic program for detecting installed Moxa Smartio boards. | ||
| 40 | - msmon Monitor program to observe data count and line status signals. | ||
| 41 | - msterm A simple terminal program which is useful in testing serial | ||
| 42 | ports. | ||
| 43 | - io-irq.exe Configuration program to setup ISA boards. Please note that | ||
| 44 | this program can only be executed under DOS. | ||
| 45 | |||
| 46 | All the drivers and utilities are published in form of source code under | ||
| 47 | GNU General Public License in this version. Please refer to GNU General | ||
| 48 | Public License announcement in each source code file for more detail. | ||
| 49 | |||
| 50 | In Moxa's ftp sites, you may always find latest driver at | ||
| 51 | ftp://ftp.moxa.com or ftp://ftp.moxa.com.tw. | ||
| 52 | |||
| 53 | This version of driver can be installed as Loadable Module (Module driver) | ||
| 54 | or built-in into kernel (Static driver). You may refer to following | ||
| 55 | installation procedure for suitable one. Before you install the driver, | ||
| 56 | please refer to hardware installation procedure in the User's Manual. | ||
| 57 | |||
| 58 | We assume the user should be familiar with following documents. | ||
| 59 | - Serial-HOWTO | ||
| 60 | - Kernel-HOWTO | ||
| 61 | |||
| 62 | ----------------------------------------------------------------------------- | ||
| 63 | 2. System Requirement | ||
| 64 | - Hardware platform: Intel x86 or Alpha machine | ||
| 65 | - Kernel version: 2.0.3x or 2.2.x | ||
| 66 | - gcc version 2.72 or later | ||
| 67 | - Maximum 4 boards can be installed in combination | ||
| 68 | |||
| 69 | ----------------------------------------------------------------------------- | ||
| 70 | 3. Installation | ||
| 71 | |||
| 72 | 3.1 Hardware installation | ||
| 73 | |||
| 74 | There are two types of buses, ISA and PCI, for Smartio family multiport | ||
| 75 | board. | ||
| 76 | |||
| 77 | ISA board | ||
| 78 | --------- | ||
| 79 | You'll have to configure CAP address, I/O address, Interrupt Vector | ||
| 80 | as well as IRQ before installing this driver. Please refer to hardware | ||
| 81 | installation procedure in User's Manual before proceed any further. | ||
| 82 | Please make sure the JP1 is open after the ISA board is set properly. | ||
| 83 | |||
| 84 | PCI board | ||
| 85 | --------- | ||
| 86 | You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict | ||
| 87 | with other ISA devices. Please refer to hardware installation | ||
| 88 | procedure in User's Manual in advance. | ||
| 89 | |||
| 90 | IRQ Sharing | ||
| 91 | ----------- | ||
| 92 | Each port within the same multiport board shares the same IRQ. Up to | ||
| 93 | 4 Moxa Smartio Family multiport boards can be installed together on | ||
| 94 | one system and they can share the same IRQ. | ||
| 95 | |||
| 96 | 3.2 Driver files and device naming convention | ||
| 97 | |||
| 98 | The driver file may be obtained from ftp, CD-ROM or floppy disk. The | ||
| 99 | first step, anyway, is to copy driver file "mxser.tgz" into specified | ||
| 100 | directory. e.g. /moxa. The execute commands as below. | ||
| 101 | |||
| 102 | # cd /moxa | ||
| 103 | # tar xvf /dev/fd0 | ||
| 104 | or | ||
| 105 | # cd /moxa | ||
| 106 | # cp /mnt/cdrom/<driver directory>/mxser.tgz . | ||
| 107 | # tar xvfz mxser.tgz | ||
| 108 | |||
| 109 | You may find all the driver and utilities files in /moxa/mxser. | ||
| 110 | Following installation procedure depends on the model you'd like to | ||
| 111 | run the driver. If you prefer module driver, please refer to 3.3. | ||
| 112 | If static driver is required, please refer to 3.4. | ||
| 113 | |||
| 114 | Dialin and callout port | ||
| 115 | ----------------------- | ||
| 116 | This driver remains traditional serial device properties. There're | ||
| 117 | two special file name for each serial port. One is dial-in port | ||
| 118 | which is named "ttyMxx". For callout port, the naming convention | ||
| 119 | is "cumxx". | ||
| 120 | |||
| 121 | Device naming when more than 2 boards installed | ||
| 122 | ----------------------------------------------- | ||
| 123 | Naming convention for each Smartio multiport board is pre-defined | ||
| 124 | as below. | ||
| 125 | |||
| 126 | Board Num. Dial-in Port Callout port | ||
| 127 | 1st board ttyM0 - ttyM7 cum0 - cum7 | ||
| 128 | 2nd board ttyM8 - ttyM15 cum8 - cum15 | ||
| 129 | 3rd board ttyM16 - ttyM23 cum16 - cum23 | ||
| 130 | 4th board ttyM24 - ttym31 cum24 - cum31 | ||
| 131 | |||
| 132 | Board sequence | ||
| 133 | -------------- | ||
| 134 | This driver will activate ISA boards according to the parameter set | ||
| 135 | in the driver. After all specified ISA board activated, PCI board | ||
| 136 | will be installed in the system automatically driven. | ||
| 137 | Therefore the board number is sorted by the CAP address of ISA boards. | ||
| 138 | For PCI boards, their sequence will be after ISA boards and C168H/PCI | ||
| 139 | has higher priority than C104H/PCI boards. | ||
| 140 | |||
| 141 | 3.3 Module driver configuration | ||
| 142 | Module driver is easiest way to install. If you prefer static driver | ||
| 143 | installation, please skip this paragraph. | ||
| 144 | 1. Find "Makefile" in /moxa/mxser, then run | ||
| 145 | |||
| 146 | # make install | ||
| 147 | |||
| 148 | The driver files "mxser.o" and utilities will be properly compiled | ||
| 149 | and copied to system directories respectively.Then run | ||
| 150 | |||
| 151 | # insmod mxser | ||
| 152 | |||
| 153 | to activate the modular driver. You may run "lsmod" to check | ||
| 154 | if "mxser.o" is activated. | ||
| 155 | |||
| 156 | 2. Create special files by executing "msmknod". | ||
| 157 | # cd /moxa/mxser/driver | ||
| 158 | # ./msmknod | ||
| 159 | |||
| 160 | Default major numbers for dial-in device and callout device are | ||
| 161 | 174, 175. Msmknod will delete any special files occupying the same | ||
| 162 | device naming. | ||
| 163 | |||
| 164 | 3. Up to now, you may manually execute "insmod mxser" to activate | ||
| 165 | this driver and run "rmmod mxser" to remove it. However, it's | ||
| 166 | better to have a boot time configuration to eliminate manual | ||
| 167 | operation. | ||
| 168 | Boot time configuration can be achieved by rc file. Run following | ||
| 169 | command for setting rc files. | ||
| 170 | |||
| 171 | # cd /moxa/mxser/driver | ||
| 172 | # cp ./rc.mxser /etc/rc.d | ||
| 173 | # cd /etc/rc.d | ||
| 174 | |||
| 175 | You may have to modify part of the content in rc.mxser to specify | ||
| 176 | parameters for ISA board. Please refer to rc.mxser for more detail. | ||
| 177 | Find "rc.serial". If "rc.serial" doesn't exist, create it by vi. | ||
| 178 | Add "rc.mxser" in last line. Next, open rc.local by vi | ||
| 179 | and append following content. | ||
| 180 | |||
| 181 | if [ -f /etc/rc.d/rc.serial ]; then | ||
| 182 | sh /etc/rc.d/rc.serial | ||
| 183 | fi | ||
| 184 | |||
| 185 | 4. Reboot and check if mxser.o activated by "lsmod" command. | ||
| 186 | 5. If you'd like to drive Smartio ISA boards in the system, you'll | ||
| 187 | have to add parameter to specify CAP address of given board while | ||
| 188 | activating "mxser.o". The format for parameters are as follows. | ||
| 189 | |||
| 190 | insmod mxser ioaddr=0x???,0x???,0x???,0x??? | ||
| 191 | | | | | | ||
| 192 | | | | +- 4th ISA board | ||
| 193 | | | +------ 3rd ISA board | ||
| 194 | | +------------ 2nd ISA board | ||
| 195 | +------------------- 1st ISA board | ||
| 196 | |||
| 197 | 3.4 Static driver configuration | ||
| 198 | |||
| 199 | 1. Create link | ||
| 200 | # cd /usr/src/linux/drivers/char | ||
| 201 | # ln -s /moxa/mxser/driver/mxser.c mxser.c | ||
| 202 | |||
| 203 | 2. Add CAP address list for ISA boards | ||
| 204 | In module mode, the CAP address for ISA board is given by | ||
| 205 | parameter. In static driver configuration, you'll have to | ||
| 206 | assign it within driver's source code. If you will not | ||
| 207 | install any ISA boards, you may skip to next portion. | ||
| 208 | The instructions to modify driver source code are as | ||
| 209 | below. | ||
| 210 | a. # cd /moxa/mxser/driver | ||
| 211 | # vi mxser.c | ||
| 212 | b. Find the array mxserBoardCAP[] as below. | ||
| 213 | |||
| 214 | static int mxserBoardCAP[] | ||
| 215 | = {0x00, 0x00, 0x00, 0x00}; | ||
| 216 | |||
| 217 | c. Change the address within this array using vi. For | ||
| 218 | example, to driver 2 ISA boards with CAP address | ||
| 219 | 0x280 and 0x180 as 1st and 2nd board. Just to change | ||
| 220 | the source code as follows. | ||
| 221 | |||
| 222 | static int mxserBoardCAP[] | ||
| 223 | = {0x280, 0x180, 0x00, 0x00}; | ||
| 224 | |||
| 225 | 3. Modify tty_io.c | ||
| 226 | # cd /usr/src/linux/drivers/char/ | ||
| 227 | # vi tty_io.c | ||
| 228 | Find pty_init(), insert "mxser_init()" as | ||
| 229 | |||
| 230 | pty_init(); | ||
| 231 | mxser_init(); | ||
| 232 | |||
| 233 | 4. Modify tty.h | ||
| 234 | # cd /usr/src/linux/include/linux | ||
| 235 | # vi tty.h | ||
| 236 | Find extern int tty_init(void), insert "mxser_init()" as | ||
| 237 | |||
| 238 | extern int tty_init(void); | ||
| 239 | extern int mxser_init(void); | ||
| 240 | |||
| 241 | 5. Modify Makefile | ||
| 242 | # cd /usr/src/linux/drivers/char | ||
| 243 | # vi Makefile | ||
| 244 | Find L_OBJS := tty_io.o ...... random.o, add | ||
| 245 | "mxser.o" at last of this line as | ||
| 246 | L_OBJS := tty_io.o ....... mxser.o | ||
| 247 | |||
| 248 | 6. Rebuild kernel | ||
| 249 | The following are for Linux kernel rebuilding,for your reference only. | ||
| 250 | For appropriate details, please refer to the Linux document. | ||
| 251 | |||
| 252 | If 'lilo' utility is installed, please use 'make zlilo' to rebuild | ||
| 253 | kernel. If 'lilo' is not installed, please follow the following steps. | ||
| 254 | |||
| 255 | a. cd /usr/src/linux | ||
| 256 | b. make clean /* take a few minutes */ | ||
| 257 | c. make bzImage /* take probably 10-20 minutes */ | ||
| 258 | d. Backup original boot kernel. /* optional step */ | ||
| 259 | e. cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz | ||
| 260 | f. Please make sure the boot kernel (vmlinuz) is in the | ||
| 261 | correct position. If you use 'lilo' utility, you should | ||
| 262 | check /etc/lilo.conf 'image' item specified the path | ||
| 263 | which is the 'vmlinuz' path, or you will load wrong | ||
| 264 | (or old) boot kernel image (vmlinuz). | ||
| 265 | g. chmod 400 /vmlinuz | ||
| 266 | h. lilo | ||
| 267 | i. rdev -R /vmlinuz 1 | ||
| 268 | j. sync | ||
| 269 | |||
| 270 | Note that if the result of "make zImage" is ERROR, then you have to | ||
| 271 | go back to Linux configuration Setup. Type "make config" in directory | ||
| 272 | /usr/src/linux or "setup". | ||
| 273 | |||
| 274 | Since system include file, /usr/src/linux/include/linux/interrupt.h, | ||
| 275 | is modified each time the MOXA driver is installed, kernel rebuilding | ||
| 276 | is inevitable. And it takes about 10 to 20 minutes depends on the | ||
| 277 | machine. | ||
| 278 | |||
| 279 | 7. Make utility | ||
| 280 | # cd /moxa/mxser/utility | ||
| 281 | # make install | ||
| 282 | |||
| 283 | 8. Make special file | ||
| 284 | # cd /moxa/mxser/driver | ||
| 285 | # ./msmknod | ||
| 286 | |||
| 287 | 9. Reboot | ||
| 288 | |||
| 289 | 3.5 Custom configuration | ||
| 290 | Although this driver already provides you default configuration, you | ||
| 291 | still can change the device name and major number.The instruction to | ||
| 292 | change these parameters are shown as below. | ||
| 293 | |||
| 294 | Change Device name | ||
| 295 | ------------------ | ||
| 296 | If you'd like to use other device names instead of default naming | ||
| 297 | convention, all you have to do is to modify the internal code | ||
| 298 | within the shell script "msmknod". First, you have to open "msmknod" | ||
| 299 | by vi. Locate each line contains "ttyM" and "cum" and change them | ||
| 300 | to the device name you desired. "msmknod" creates the device names | ||
| 301 | you need next time executed. | ||
| 302 | |||
| 303 | Change Major number | ||
| 304 | ------------------- | ||
| 305 | If major number 30 and 35 had been occupied, you may have to select | ||
| 306 | 2 free major numbers for this driver. There are 3 steps to change | ||
| 307 | major numbers. | ||
| 308 | |||
| 309 | 1. Find free major numbers | ||
| 310 | In /proc/devices, you may find all the major numbers occupied | ||
| 311 | in the system. Please select 2 major numbers that are available. | ||
| 312 | e.g. 40, 45. | ||
| 313 | 2. Create special files | ||
| 314 | Run /moxa/mxser/driver/msmknod to create special files with | ||
| 315 | specified major numbers. | ||
| 316 | 3. Modify driver with new major number | ||
| 317 | Run vi to open /moxa/mxser/driver/mxser.c. Locate the line | ||
| 318 | contains "MXSERMAJOR". Change the content as below. | ||
| 319 | #define MXSERMAJOR 40 | ||
| 320 | #define MXSERCUMAJOR 45 | ||
| 321 | 4. Run # make install in /moxa/mxser/driver. | ||
| 322 | |||
| 323 | 3.6 Verify driver installation | ||
| 324 | You may refer to /var/log/messages to check the latest status | ||
| 325 | log reported by this driver whenever it's activated. | ||
| 326 | ----------------------------------------------------------------------------- | ||
| 327 | 4. Utilities | ||
| 328 | There are 3 utilities contained in this driver. They are msdiag, msmon and | ||
| 329 | msterm. These 3 utilities are released in form of source code. They should | ||
| 330 | be compiled into executable file and copied into /usr/bin. | ||
| 331 | |||
| 332 | msdiag - Diagnostic | ||
| 333 | -------------------- | ||
| 334 | This utility provides the function to detect what Moxa Smartio multiport | ||
| 335 | board exists in the system. | ||
| 336 | |||
| 337 | msmon - Port Monitoring | ||
| 338 | ----------------------- | ||
| 339 | This utility gives the user a quick view about all the MOXA ports' | ||
| 340 | activities. One can easily learn each port's total received/transmitted | ||
| 341 | (Rx/Tx) character count since the time when the monitoring is started. | ||
| 342 | Rx/Tx throughputs per second are also reported in interval basis (e.g. | ||
| 343 | the last 5 seconds) and in average basis (since the time the monitoring | ||
| 344 | is started). You can reset all ports' count by <HOME> key. <+> <-> | ||
| 345 | (plus/minus) keys to change the displaying time interval. Press <ENTER> | ||
| 346 | on the port, that cursor stay, to view the port's communication | ||
| 347 | parameters, signal status, and input/output queue. | ||
| 348 | |||
| 349 | msterm - Terminal Emulation | ||
| 350 | --------------------------- | ||
| 351 | This utility provides data sending and receiving ability of all tty ports, | ||
| 352 | especially for MOXA ports. It is quite useful for testing simple | ||
| 353 | application, for example, sending AT command to a modem connected to the | ||
| 354 | port or used as a terminal for login purpose. Note that this is only a | ||
| 355 | dumb terminal emulation without handling full screen operation. | ||
| 356 | ----------------------------------------------------------------------------- | ||
| 357 | 5. Setserial | ||
| 358 | |||
| 359 | Supported Setserial parameters are listed as below. | ||
| 360 | |||
| 361 | uart set UART type(16450-->disable FIFO, 16550A-->enable FIFO) | ||
| 362 | close_delay set the amount of time(in 1/100 of a second) that DTR | ||
| 363 | should be kept low while being closed. | ||
| 364 | closing_wait set the amount of time(in 1/100 of a second) that the | ||
| 365 | serial port should wait for data to be drained while | ||
| 366 | being closed, before the receiver is disable. | ||
| 367 | spd_hi Use 57.6kb when the application requests 38.4kb. | ||
| 368 | spd_vhi Use 115.2kb when the application requests 38.4kb. | ||
| 369 | spd_normal Use 38.4kb when the application requests 38.4kb. | ||
| 370 | |||
| 371 | ----------------------------------------------------------------------------- | ||
| 372 | 6. Troubleshooting | ||
| 373 | |||
| 374 | The boot time error messages and solutions are stated as clearly as | ||
| 375 | possible. If all the possible solutions fail, please contact our technical | ||
| 376 | support team to get more help. | ||
| 377 | |||
| 378 | Error msg: More than 4 Moxa Smartio family boards found. Fifth board and | ||
| 379 | after are ignored. | ||
| 380 | Solution: | ||
| 381 | To avoid this problem, please unplug fifth and after board, because Moxa | ||
| 382 | driver supports up to 4 boards. | ||
| 383 | |||
| 384 | Error msg: Request_irq fail, IRQ(?) may be conflict with another device. | ||
| 385 | Solution: | ||
| 386 | Other PCI or ISA devices occupy the assigned IRQ. If you are not sure | ||
| 387 | which device causes the situation,please check /proc/interrupts to find | ||
| 388 | free IRQ and simply change another free IRQ for Moxa board. | ||
| 389 | |||
| 390 | Error msg: Board #: C1xx Series(CAP=xxx) interrupt number invalid. | ||
| 391 | Solution: | ||
| 392 | Each port within the same multiport board shares the same IRQ. Please set | ||
| 393 | one IRQ (IRQ doesn't equal to zero) for one Moxa board. | ||
| 394 | |||
| 395 | Error msg: No interrupt vector be set for Moxa ISA board(CAP=xxx). | ||
| 396 | Solution: | ||
| 397 | Moxa ISA board needs an interrupt vector.Please refer to user's manual | ||
| 398 | "Hardware Installation" chapter to set interrupt vector. | ||
