47
48   If a compatibility problem occurs, please contact Moxa at
49   support@moxa.com.tw.
50
51   In addition to device driver, useful utilities are also provided in this
52   version. They are:
53
54    - msdiag
55		 Diagnostic program for displaying installed Moxa
56                 Smartio/Industio boards.
57    - msmon
58		 Monitor program to observe data count and line status signals.
59    - msterm     A simple terminal program which is useful in testing serial
60	         ports.
61
62   All the drivers and utilities are published in form of source code under
63   GNU General Public License in this version. Please refer to GNU General
64   Public License announcement in each source code file for more detail.
65
66   In Moxa's Web sites, you may always find the latest driver at
67   https://www.moxa.com/.
68
69   This version of driver can be installed as a Loadable Module (Module driver)
70   or built-in into kernel (Static driver). Before you install the driver,
71   please refer to hardware installation procedure in the User's Manual.
72
73   We assume the user should be familiar with following documents:
74
75   - Serial-HOWTO
76   - Kernel-HOWTO
77
782. System Requirement
79^^^^^^^^^^^^^^^^^^^^^
80
81   - Maximum 4 boards can be installed in combination
82
833. Installation
84^^^^^^^^^^^^^^^
85
863.1 Hardware installation
87=========================
88
89PCI/UPCI board
90--------------
91
92   You may need to adjust IRQ usage in BIOS to avoid IRQ conflict with other
93   ISA devices. Please refer to hardware installation procedure in User's
94   Manual in advance.
95
96PCI IRQ Sharing
97---------------
98
99   Each port within the same multiport board shares the same IRQ. Up to
100   4 Moxa Smartio/Industio PCI Family multiport boards can be installed
101   together on one system and they can share the same IRQ.
102
103
104
1053.2 Device naming convention
106============================
107
108   The device node is named "ttyMxx".
109
110Device naming when more than 2 boards installed
111-----------------------------------------------
112
113   Naming convention for each Smartio/Industio multiport board is
114   pre-defined as below.
115
116   ============ ===============
117   Board Num.	Device node
118   1st board	ttyM0  - ttyM7
119   2nd board	ttyM8  - ttyM15
120   3rd board	ttyM16 - ttyM23
121   4th board	ttyM24 - ttyM31
122   ============ ===============
123
1244. Utilities
125^^^^^^^^^^^^
126
127   There are 3 utilities contained in this driver. They are msdiag, msmon and
128   msterm. These 3 utilities are released in form of source code. They should
129   be compiled into executable file and copied into /usr/bin.
130
131msdiag - Diagnostic
132===================
133
134   This utility provides the function to display what Moxa Smartio/Industio
135   board was found by the driver in the system.
136
137msmon - Port Monitoring
138=======================
139
140   This utility gives the user a quick view about all the MOXA ports'
141   activities. One can easily learn each port's total received/transmitted
142   (Rx/Tx) character count since the time when the monitoring is started.
143
144   Rx/Tx throughputs per second are also reported in interval basis (e.g.
145   the last 5 seconds) and in average basis (since the time the monitoring
146   is started). You can reset all ports' count by <HOME> key. <+> <->
147   (plus/minus) keys to change the displaying time interval. Press <ENTER>
148   on the port, that cursor stay, to view the port's communication
149   parameters, signal status, and input/output queue.
150
151msterm - Terminal Emulation
152===========================
153
154   This utility provides data sending and receiving ability of all tty ports,
155   especially for MOXA ports. It is quite useful for testing simple
156   application, for example, sending AT command to a modem connected to the
157   port or used as a terminal for login purpose. Note that this is only a
158   dumb terminal emulation without handling full screen operation.
159
1605. Setserial
161^^^^^^^^^^^^
162
163   Supported Setserial parameters are listed as below.
164
165   ============== =============================================================
166   uart		  set UART type(16450 --> disable FIFO, 16550A --> enable FIFO)
167   close_delay	  set the amount of time (in 1/100 of a second) that DTR
168		  should be kept low while being closed.
169   closing_wait   set the amount of time (in 1/100 of a second) that the
170		  serial port should wait for data to be drained while
171		  being closed, before the receiver is disabled.
172   spd_hi	  Use 57.6kb when the application requests 38.4kb.
173   spd_vhi	  Use 115.2kb when the application requests 38.4kb.
174   spd_shi	  Use 230.4kb when the application requests 38.4kb.
175   spd_warp	  Use 460.8kb when the application requests 38.4kb.
176   spd_normal	  Use 38.4kb when the application requests 38.4kb.
177   spd_cust	  Use the custom divisor to set the speed when the
178		  application requests 38.4kb.
179   divisor	  This option sets the custom division.
180   baud_base	  This option sets the base baud rate.
181   ============== =============================================================
182
1836. Troubleshooting
184^^^^^^^^^^^^^^^^^^
185
186   The boot time error messages and solutions are stated as clearly as
187   possible. If all the possible solutions fail, please contact our technical
188   support team to get more help.
189
190
191   Error msg:
192	      More than 4 Moxa Smartio/Industio family boards found. Fifth board
193              and after are ignored.
194
195   Solution:
196   To avoid this problem, please unplug fifth and after board, because Moxa
197   driver supports up to 4 boards.
