I use the hyperterminal to communicate and send commands to serial
port COM1.
On the hyperterminal window, I used to type such a command:

AT+ZV SPPCONNECT.......

This command is sent to the device connected to the COM1 port.

Now I want to cancel the hyperterminal, and sue a Java program.
I used the javax.comm library to build a java application that
communicates with the COM1 port.

Inside that program, I connected to the COM1 port. How do I send that
text command from inside the java program to the COM1 port. There is a
method called (send) inside the (serialport) class, do I just say:

serialport.send "AT+ZV SPPCONNECT.......".

I mean, is sending text commands through the hyperterminal simply
equivalent to sending those text commands to the COM1 port using the
java application described above.

Now: Is sending the text command to the COM1

It seems you are referring to the examples given at
<http://java.sun.com/products/javacomm/reference/docs/API_users_guide_3.html>,
don't you?

This is not even syntactically correct (hence I assume you are still a
very beginner in Java). It will be probably more like
OutputStream outputStream = serialPort.getOutputStream();
outputStream.write("AT+ZV SPPCONNECT.......".getBytes());
outputStream.flush();

I suppose so (although I have no practical experience with javax.comm).
But using javax.comm is not only about sending bytes. It is also about
waiting for responses (and that is probably the more difficult part).

Be warned: Before you will have any chance for mastering the javax.comm
package, there is much work for you to prepare the basics:
(1) Learn the Java language (the syntax and concepts)
(2) Learn the basic Java classes (like OutputStream)
(3) Read the API docs at
