Title: java SerialPort program doesn\'t work on Z???
Post by: liferey on March 30, 2004, 11:12:41 am

I downloaded SimpleRead.java from

http://java.sun.com/developer/releases/jav...SimpleRead.java (http://java.sun.com/developer/releases/javacomm/SimpleRead.java)

It worked well on a linux desktop. But when I move it to Z, it said
\"No /dev/ttyS0\".... This java program couldn\'t find any CommPortIdentifier.

I got the comm.jar for Zaurus from
http://s88074083.onlinehome.us/Zaurus/Index.htm (http://s88074083.onlinehome.us/Zaurus/Index.htm)
and it is saved in /home/QtPalmtop/java/comm.jar. I am pretty sure ttyS0 is open because I can use a C program to read from it. What could be the problem?

I\'ve searched all the messages and nobody\'s ever had this problem before. Am I missing some real obvious steps here? I will be forever indebted for your help!

I've noticed some strange Java bugs with my 6000L that I didn't have with the Jeode JVM on my trusty old 5000d.  Is it possible to just scrap the newer JVM & run Jeode on the 6000L?  I wonder what the maximum screen resolution would be with Jeode.  Anyone know?  Is there an alternative (other than Jeode) that I can run on the 6000?  Something less flakey?
