In “Port Feature Settings” sub-dialog, port feature [Terminal] is the only choice
if On Board Line Discipline is set to “Enable”. This is good for terminal
application users.
However, if On-Board Line Discipline is set to “Disable”, port feature could be
either [Transparent] or [Terminal]. In case of [Terminal], all the tty line
discipline jobs will be done on host which surely is a burden to the host. In case
of [Transparent], no time-consuming tty line discipline is applied for the port
except flow control, thus non-terminal applications such as data acquisition will
benefit from it, e.g. gain better throughput and performance. The
C218Turbo/PCI firmware will do Xon/Xoff flow control and H/W flow control if
ixon/ixany or ixoff are set via ioctl() system call. In this case, the Non-Modem

UNIX
Programming the MOXA Ports
The system calls that apply to standard tty port can also be applied to MOXA port
since MOXA port conforms to UNIX tty standard. System calls are like open(),
ioctl(), read(), write(), close(), etc. Please refer to your UNIX Programmer's
Reference manual.
However, these system services only provide limited functions and thus may not
satisfy the sophisticated programmers' need. In order to meet the user's special
purpose, MOXA supports extended services through ioctl() command, which are:
1. MIBUFED (= 0x401) To get byte count in input buffer.
2. MOBUFED (= 0x402) To get byte count in output buffer.
3. MTCRTS (= 0x403) To control RTS output signal.
4. MTCDTR (= 0x404) To control DTR output signal.
5. MLOWATER (= 0x405) To set output buffer low water level.
6. MSTATUS (= 0x407) To read modem line status (CTS/DSR/DCD).
7. MHWFLOW (= 0x40e) To enable/disable the hardware flow control.
The next section details all the commands.
Extended UNIX Ioctl() Commands
The following lists the syntax of MOXA extended functions for both non-SVR4.x
and SVR4.x UNIX. The variable moxa_fd is the returned file descriptor by open() a
specific MOXA port. For example,
int moxa_fd;
moxa_fd = open("/dev/ttya11",O_RDWR);
1. MIBUFED
This function let you know how many bytes queued in input buffer when this
function is issued.

Note: Due to the characteristics of STREAMS driver, the returned count of
bytes buffered only reflect the data buffered on MOXA board, not
including the data buffered in STREAMS queue. In this case, the count
is for reference only. For example, returned count may always be zero,
but there still are data buffered in STREAMS queue.

5. MLOWATER
Serial Programming Tools
Sometimes the application software may not be able to write any further data to
the output buffer because of the output buffer being full. The application has to
wait until the output buffer has 'enough space' again. The criteria to tell if the
output buffer has 'enough space' is whether the output buffer reached its 'low
water' level. That is the output buffer will accept further data only when the 'low
water' level is reached.
If the 'low water' value is relatively small, you may find that the output buffer
become empty before you write another block of data (this is quite possible
because UNIX is time-sharing multitasking environment). This will result in
discontinuous data transmission. In a timeout-sensitive application, e.g.
facsimile (FAX) transmission, discontinuous data may falter the operation.
The default 'low water' is 512 bytes. You can enlarge it but better not exceed one
half of the output buffer. Each port's output buffer is 8K bytes.

7. MHWFLOW
This function is used to enable/disable hardware flow control. The first open()
function of a port will set the hardware flow control bits on or off depending on
the [
RTS/CTS Hardware Flow Control] configuration in mxadm. However,
users might want to control the DTR or RTS signal on their will, thus the RTS
flow control bit should be turned off (HWFLowControlOff) in order to take
over the control of DTR or RTS signal via function MTCRTS or MTCDTR.
MTCRTS and MTCDTR can be effective only after the RTS flow control bit of
MHWFLOW is turned off.

Utilities
Port Monitoring
You can use the administration utility, mxadm, to monitor port activity and to do
terminal emulation, which are details as follows.
This utility gives you a quick view about all the MOXA ports' activities. You 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.

Terminal Emulator
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.
Besides, data scope function with pattern/file transfer is provided.

How to transmit and receive data under Windows NT and
Windows 95/98
We recommend you to configure Intellio C218Turbo/PCI ports as follows in order to
acquire precise timing control in RS-485 2-wire transmission.
First set the “Transmission Mode” in the configuration program to “Classical”.
UART FIFO status has no effect under the circumstance.
There are 2 solutions to control RS-485 2-wire transmission.
Solution 1
The following model is common in RS-485 2-wire transmission.
sio_SetWriteTimeouts(port, 0); /* Set sio_write() into block mode */
sio_RTS(port, 1); /* Turn on RTS signal. The RS-485
port is ready for transmitting data. */
sio_write(port, buff, 10); /* Write 10 byte characters in "buff".
The function blocks until last
character transmitted */
sio_RTS(port, 0); /* Turn off RTS signal. The RS-485
port is ready for receiving data. */
sio_read(port, buff, 10); /* Read 10 bytes */
Intellio C218Turbo /PCI User's Manual 4-15
Solution 2
There's a dedicated RS-485 function in PComm library. It integrates the above
functions of solution 1 regarding sending data as one.
sio_putb_x(port, buff, tick ); /* 1. Turn on RTS and ready for
transmitting data.
2. Send data.
3. Wait for tick time.
4. Turn off RTS and ready for
receiving data. */

RS-422/485 Impedance Matching
For RS-422/485 serial communications, when an electrical signal travels through
two different resistance junctions in a transmission line, the impedance mismatch
will sometimes cause signal reflection. Signal reflection causes signal distortion,
which in turn will contribute communication errors. The solution to this problem is
to establish the same impedance at the line ends as in the line itself by terminating
them with resistors.
The value of the termination resistor should equal the characteristic impedance of
the transmission line. The resistors should be added

PCI
The 32-bit Intellio C218Turbo/PCI board complies with PCI Spec. 2.1. Hardware
configuration for IRQ and Memory addresses is automatically assigned by PCI
BIOS. Hence, it is a must to
driver.
Unlike ISA slots, different PCI slots in the same PC may have different bus numbers
and device numbers with respect to PCI specifications. The same PCI board will
have different system configurations if switched to a different PCI slot, which may
be called
slot-sensitive or slot-dependent. This may also apply to PCI slots in PC of
different mother board, which may use
some use 17, 18, 19, and 20 for identifying the respective PCI slot but some use 11,
12, 13 and 14.
Due to the
slot-dependency, it is necessary to re-configure the software driver
once the board is plugged in different PCI slots.

Dual-Ported RAM
There is 512 KB of dual-ported DRAM on the Intellio C218Turbo/PCI, which is
used as a data buffer and memory map device for the mother board. It is called
"dual-ported" because it is accessed by both mother board CPU and the Intellio
C218
Turbo/PCI on-board CPU. Generally speaking, the memory access time is much

please do keep in mind the order you plug the boards
faster than normal I/O access.
All messages and data are transferred through this 512 KB dual-ported memory.
The buffer area appears as normal 16-bit memory to the PC AT I/O channel.
Every
Intellio C218Turbo/PCI only occupies 16 KB of memory space (window) from
the system point of view.
UART 16C550C
The UART chip, 16C550C, is an intelligent asynchronous controller capable of
supporting one full duplex channel that transfers data at
To increase the overall data throughput, special features such as on-chip FIFO and
on-chip hardware flow control are used to reduce the number of interrupts to the on
board CPU and to prevent any loss of valuable data.
