Uncle George:

Which specific JDK are you using?  I can take a quick look at whats going
on.

The IBM JDK has been shipping something of a comm.jar.  Last time I took
a look it was remapping /dev/ttyS0 to COM1 and such.  That could be what
you are running into.

Mixing IBM/Sun comm.jar and rxtx 1.5 would be a bad thing.  rxtx 1.4 is
intended to work with comm.jar.  1.5 is a replacment for comm.jar.

Interesting to hear about the mem leaks with JDK 1.3.  I had problems with
it also (Mainly on win32 though).

Same Uncle George that did the Blackdown Alpha JDK/Linux work?
