(Sorry for the previous post, keyboard error)
This is strange, because you are getting the following message (which is
a known "warning" we need to fix)
> 2007/10/25 09:08:50.062 asynManager::asynConnectCallback, port L0
error calling
> asynCommon->connect L0 addr 0 vxiConnect request but already connected
So it says port LO is already connected.
But then you get this:
> 2007/10/25 09:08:50.083 AG:RFreq: asynError in write: L0 port is not
connected
Which says the port is not connected.
