Step 4 Checking Operations with the Diagnosis
Program
Use the diagnosis program to check that the board and driver software work normally, thereby you can
confirm that they have been set up correctly.
What is the Diagnosis Program?
These programs perform some simple checks on the board operation. Two programs are provided.
Terminal program (CTstCom.exe)
Data entered from the keyboard is sent directly from the port. The function of the program is
equivalent 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
If a cross cable is not available, you can test communication using a single COM port by means of
loopback arranged by setting the switch on the connection cable box. See the figure below for the
switch settings.
