The purpose of this software is to allow the CONTEC serial communication PC cards to be used under Windows or
Linux in the same way as the standard COM ports on the PC. By installing additional PC cards, you can use COM ports
in the range COM1 to COM256.
The PC cards can be used for all types of serial co mmunicat ions such as for remote access service (RAS) and
uninterruptible power supply (UPS) applications.
Under Windows, the serial ports can be accessed using the standard Win32 API communication routines (CreateFile( ),
WriteFile( ), ReadFile( ), and SetCommState( ), etc.) The serial ports are also compatible with the Visual Basic
communication control (MSComm).
Under Linux, the serial ports are compatible with the operating system's standard tty driver. The standard rou tines
including open( ), close( ), read( ), write( ) are supported.

- The PC card cannot be properly installed unless the resources (I/O addre sses a nd i nterrup t level) f or
the PC card can be allocated. Before attempting to install the PC card, first determine what PC
resources are free to use.
- The resources used by each PC card do not de pend on t he location of t he PC cards slot or the PC card
itself. If you remove two or more PC cards that have al ready been installe d and then remount one of
them on the computer, it is unknown that which one of the sets of resources previously assigned to
the two PC Cards is assigned to the remounted PC card. In this case, you must check the resource
settings.

Step 4 Checking Operations with the Diagnosis Program
Use the diagnosis program to check that the PC card and driver software work normally, thereby you ca n
confirm that they have been set up correctly.
What is the Diagnosis Program?
These programs perform some simple checks on the PC card operation. Two programs are provided.
Terminal program (CTstCom.exe)
Data entered from the keyboard is s ent dir ectly fr om th e port. T he func tion of the progr am is eq uivale nt
to the Hyper Terminal program provided with Windows.
Serial Communications Diagnostic Program (CommChk.exe)
Performs actual communications and indicates whether the results are correct or not (error).
The following describes the procedure for testing using the serial communications diagnostic program
(CommChk.exe).
Check Method
Obtain an RS-232C crossed cable or a loopback connector. If using a cross ed cable, connect to th e
COM port on the PC. If using a loopback connector, you can perform the check using a single COM port.
The figure below shows the wiring connections for a loopback connector.

4. Functions
This section describes the functions of the PC Card.
Communication Function
Serial Data Transmission
COM-1(PM) sends and receives data using the RS-232C communication standard.
COM-1D(PM) sends and receives data using the RS-422A/485 communication standard.
The baud rate can be set by software to between 2 and 115,200bps.
RS-232C Control Lines (COM-1(PM))
All ports include the RTS, CTS, DTR, and DSR control lines.
The lines can be controlled or monitored by software from the application
RS-422A/485 Control Lines (COM-1D(PM))
All ports include the RTS+, RTS-, CTS+, and CTS- control lines.
The lines can be controlled or monitored by software from the application
4. Functions
Send and Receive Data Buffers
The card contains a 16byte send buffer and 16byte receive buffer.
The buffers operate as FIFO buffers and help reduce the load on the CPU for high-speed
communications or system operation.
The data buffer operation (whether to use FIFO operation, FIFO trigger size) can be set using Device
Manager (on Windows XP, 2000, Me, 98, and 95). On Windo ws NT, only wh ethe r to use FIFO
operation can be specified using [Control Panel] - [Serial Ports].
The FIFO trigger is the data buffer size that determines the timing of the hardware interrupt. However,
this setting and function only applies to the receive buffer and not to the send buffer.
Setting a large FIFO trigger size lightens the load on the CPU by reducing the number of hardware
interrupts generated by sending or receiving data.
However, as data is not actually sent or received until a certain amount is present, a delay may occur in
sending data to the other device or in notifying the application that data has been received.
Alternatively, setting a small FIFO trigger size or disabling FIFO operation increases the speed of data
sending and receiving but increases the load on the CPU and risks received data being missed.
As the FIFO buffer size is variable, you can adjust this setting to achieve optimum performance for your
system.
COM-1(PM), COM-1D(PM)

Page 37
4. Functions
Setting the Baud Rate
The baud rate is set by specifying the divide register value (divisor).
Baud Rate: 2 to 115,200bps
Table 4.1 lists the divisor settings for common baud rates when using the COM Setup Disk and
API-PAC(W32).
Table 4.1. Exampl e Se tt ing s fo r Common Baud Rates
Baud Rate Divisor
2 57600 --- 150 768 --- 7200 16 --4 28800 --- 300 384 --- 9600 12 --5 23040 --- 600 192 --- 14400 8 ---

110 1047 0.026 3600 32 --- 115200 1 ---
134.5 857 0.058 4800 24 --- ---
Use the formula below if yo u want to s et a ba ud rate other t han tho se list ed in Tabl e 4. 1. A ba ud rate can
only be set if the divisor calculated by the formula is an integer. Any digits after the decimal point
indicate that the baud rate cannot be used.
115200 ÷ Desired baud rate
Ex.) 115200 ÷ 9600bps = 12 (As the result is an in t ege r, th is ba ud ra te c an b e set. )
115200 ÷ 76800bps = 1.5 (As the result contains a fractional part, this baud rate cannot be set.)
