If you have issues setting the attenuation levels, and are seeing the error:
WARNING: error s1 -104 ifpcn: time-out, connection closed
Then you can try restarting Rxmon and IFBox on pcfs.
To do this, ssh to pcfs[hb/ke/yg] and login as superuser. The commands to issue are:
/etc/init.d/Monica.Rxmon stop /etc/init.d/Monica.Rxmon start
and similarly, for IFBox
/etc/init.d/Monica.IFBox stop /etc/init.d/Monica.IFBox start
If successful, you should see something along the lines of:
Socket created Socket bind complete Socket now listening Serial conn created Connected with 127.0.0.1:PORT# Connected with 127.0.0.1:PORT#
It may take a few seconds for the ports to clear, if you see the message:
Wait a few seconds, and try again.
