1. 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.
