[Tinyos-help] Serial Forwarder Error

[Metin K]

Hi to all,

I have just installed tinyos 2.0 following the instructions at
http://www.tinyos.net/tinyos-2.x/doc/html/install-tinyos.html. When I type
java net.tinyos.sf.SerialForwarder on the command line I have received the
error on the graphical interface of sf as follows:

Listening to serial at com1:57600
Listening for client connections on port 9002
Could not open com1: TOSComm JNI library runtime error: flush: Input/output
error
serial at com1:57600 died - restarting
Could not open com1: TOSComm JNI library runtime error: flush: Input/output
error
serial at com1:57600 died - restarting

I have changed the permissons of the files to 664 under the /dev directory,
also. What can be the reason for that?

P.S. When I type, rpm -ivh tinyos-tools-1.2.2-1.i386.rpm, I get:
Preparing...                ###########################################
[100%]
        package tinyos-tools-1.2.2-1 is already installed
When rpm -e tinyos-tools-1.2.2-1.i386.rpm; error: package
tinyos-tools-1.2.2-1.i386.rpm is not installed. There is also no tools
directory under $TOSROOT.

I have fedora core 5.

Thanks to all.
