Introduction +^^^^^^^^^^^^^^^ + + The Smartio/Industio/UPCI family Linux driver supports following multiport + boards: + + - 2 ports multiport board + CP-102U, CP-102UL, CP-102UF + CP-132U-I, CP-132UL, + CP-132, CP-132I, CP132S, CP-132IS, + (CP-102, CP-102S) + + - 4 ports multiport board + CP-104EL, + CP-104UL, CP-104JU, + CP-134U, CP-134U-I, + C104H/PCI, C104HS/PCI, + CP-114, CP-114I, CP-114S, CP-114IS, CP-114UL, + (C114HI, CT-114I), + POS-104UL, + CB-114, + CB-134I + + - 8 ports multiport board + CP-118EL, CP-168EL, + CP-118U, CP-168U, + C168H/PCI, + CB-108 + + If a compatibility problem occurs, please contact Moxa at + support@moxa.com.tw. + + In addition to device driver, useful utilities are also provided in this + version. They are: + + - msdiag + Diagnostic program for displaying installed Moxa + Smartio/Industio boards. + - msmon + Monitor program to observe data count and line status signals. + - msterm A simple terminal program which is useful in testing serial + ports. + + All the drivers and utilities are published in form of source code under + GNU General Public License in this version. Please refer to GNU General + Public License announcement in each source code file for more detail. + + In Moxa's Web sites, you may always find the latest driver at + https://www.moxa.com/. + + This version of driver can be installed as a Loadable Module (Module driver) + or built-in into kernel (Static driver). Before you install the driver, + please refer to hardware installation procedure in the User's Manual. + + We assume the user should be familiar with following documents: + + - Serial-HOWTO + - Kernel-HOWTO + +2. System Requirement +^^^^^^^^^^^^^^^^^^^^^ + + - Maximum 4 boards can be installed in combination + +3. Installation +^^^^^^^^^^^^^^^ + +3.1 Hardware installation +========================= + +PCI/UPCI board +-------------- + + You may need to adjust IRQ usage in BIOS to avoid IRQ conflict with other + ISA devices. Please refer to hardware installation procedure in User's + Manual in advance. + +PCI IRQ Sharing +--------------- + + Each port within the same multiport board shares the same IRQ. Up to + 4 Moxa Smartio/Industio PCI Family multiport boards can be installed + together on one system and they can share the same IRQ. + + + +3.2 Device naming convention +============================ + + The device node is named "ttyMxx". + +Device naming when more than 2 boards installed +----------------------------------------------- + + Naming convention for each Smartio/Industio multiport board is + pre-defined as below. + + ============ =============== + Board Num. Device node + 1st board ttyM0 - ttyM7 + 2nd board ttyM8 - ttyM15 + 3rd board ttyM16 - ttyM23 + 4th board ttyM24 - ttyM31 + ============ =============== + +4. Utilities +^^^^^^^^^^^^ + + There are 3 utilities contained in this driver. They are msdiag, msmon and + msterm. These 3 utilities are released in form of source code. They should + be compiled into executable file and copied into /usr/bin. + +msdiag - Diagnostic +=================== + + This utility provides the function to display what Moxa Smartio/Industio + board was found by the driver in the system. + +msmon - Port Monitoring +======================= + + This utility gives the user a quick view about all the MOXA ports' + activities. One can easily learn each port's total received/transmitted + (Rx/Tx) character count since the time when the monitoring is started. + + Rx/Tx throughputs per second are also reported in interval basis (e.g. + the last 5 seconds) and in average basis (since the time the monitoring + is started). You can reset all ports' count by <HOME> key. <+> <-> + (plus/minus) keys to change the displaying time interval. Press <ENTER> + on the port, that cursor stay, to view the port's communication + parameters, signal status, and input/output queue. + +msterm - Terminal Emulation +=========================== + + This utility provides data sending and receiving ability of all tty ports, + especially for MOXA ports. It is quite useful for testing simple + application, for example, sending AT command to a modem connected to the + port or used as a terminal for login purpose. Note that this is only a + dumb terminal emulation without handling full screen operation. + +5. Setserial +^^^^^^^^^^^^ + + Supported Setserial parameters are listed as below. + + ============== ============================================================= + uart set UART type(16450 --> disable FIFO, 16550A --> enable FIFO) + close_delay set the amount of time (in 1/100 of a second) that DTR + should be kept low while being closed. + closing_wait set the amount of time (in 1/100 of a second) that the + serial port should wait for data to be drained while + being closed, before the receiver is disabled. + spd_hi Use 57.6kb when the application requests 38.4kb. + spd_vhi Use 115.2kb when the application requests 38.4kb. + spd_shi Use 230.4kb when the application requests 38.4kb. + spd_warp Use 460.8kb when the application requests 38.4kb. + spd_normal Use 38.4kb when the application requests 38.4kb. + spd_cust Use the custom divisor to set the speed when the + application requests 38.4kb. + divisor This option sets the custom division. + baud_base This option sets the base baud rate. + ============== ============================================================= + +6. Troubleshooting +^^^^^^^^^^^^^^^^^^ + + The boot time error messages and solutions are stated as clearly as + possible. If all the possible solutions fail, please contact our technical + support team to get more help. + + + Error msg: + More than 4 Moxa Smartio/Industio family boards found. Fifth board + and after are ignored. + + Solution: + To avoid this problem, please unplug fifth and after board, because Moxa + driver supports up to 4 boards. |
