It is a tty_driver, not serial -- uart_driver. So move it to the tty docs dir too. (The same as the driver itself.) Signed-off-by: Jiri Slaby <jslaby@suse.cz> Link: https://lore.kernel.org/r/20220411110143.10019-5-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

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.
