Hello,everyone here!
I'm from China.
Recently I hava been studying java on connecting to short message modem.
I've download comm.jar from SUN Corporation website.
I've got connected to the com terminal, but I haven't got connected to the modem.In addition,I can use the modem through the Hyper Terminal.
If any one knows how to get connected with the modem,please tell me!Thank you very much!
I'm wating for your reply.

try
{
serialport=(SerialPort)portid.open("SimpleReadApp" , 2000);

First of all, please you a dark color when you posting a code segment next time. The color you've selected is really hard to read. And also use code tags. Read the FAQ page for more details.

More important thing is, this is a forum. You must try something and if you stuck with something please your question more clearly. This is not a code bank to do your projects. Lots of members are here ready to help you, but not in this way. :)
