Hi,

I'm wondering if someone else had same problem as mine.

I'm using socket connection between POSE and Unix
workstations, and I use StreamConnection.openInputStream ()
to get the InputStream.

My program works when I solely use InputStream.read() to
receive data byte by byte but, as one would expect, it was
very slow. However, when I tried to use read(byte[] b, int off, int len)
to "spool-read" data, I always got an IOException with not
one byte of data ever returned... What am I doing wrong?

I never had such problem with J2SE, so I'm wondering why
J2ME is implemented differently?

Also, I looked at com.sun.cldc.io.j2me.socket.Protocol.java,
and it seemed that the read(byte b[], int off, int len)
method in PrivateInputStream ignores the possibility of
Protocol.read0(byte b[], int off, int len) returning -2
as result. Could it be a bug?
