serial communication help required!!!

843849Feb 6 2003 — edited Apr 26 2004
I want to connect the cassiopeia E200 to a serial device. I have the personal java installed on the PDA for programming. Sun also provides javax.comm package. This has a serial demo example which helps you communicate with the serial port on the computer (its similar to hyperterminal) This prog. runs on my PDA and the GUI pops up but I am unable to open hte port and do anything further.
I want to have full control of the serial port (essentially want to send my own commands which the device at the other end recognizes).
Can someone please help me ...

What are you using for a serial port driver? As far as I can tell you have your choice of rxtx (jcl.jar), and teilo (CESerial.jar)?

You can download teilo from http://www.teilo.net/software/CEJavaComm/download.php?expand=/software/CEJavaComm

You can download rxtx from http://republika.pl/mho/java/comm/RXTX_iPAQ_0211.zip

hope that helps.

I do not have the Jeode JVM installed on the PDA. I have the Personal Java Runtime Environment installed. I tried the telio drivers but the Serail Demo program in the javax.comm package does not open any ports.

Please tell me if the personal java supports the telio drivers. Do I have to do something extra in order to make it run?

did you include all the packages?
you need comm.jar and CESerial.jar
you also need to make sure you have copied the dll to Windows dir.
