RE: streamDevice/Asyn Error: Businterface not found

["Mark Rivers" <rivers@cars.uchicago.edu>]

Rodney,

 

asyn autoconnect ports will do exactly as you observe, they will show as disconnected until the first I/O operation, or other operation (such as setting trace mask) that wakes up the port thread.  This is not a sign of a problem, it is normal (if a bit confusing).

 

I don't know why streamDevice is giving a connection error.

 

By coincidence I am working on some changes that will fix this behavior, so that that if pasynmanager->connectDevice is called for a port with autoConnect=1 and isConnected=0, then asynManager will queue a request to call pasynCommon->connect.  That way devices will show as connected even before any I/O or setting of trace masks has happened.  That should make things less confusing.  I got this code written before asyn 4.5 was released, but it needs more testing.  It should be included in 4.6 if it works OK.

 

Mark

Subject: streamDevice/Asyn Error: Businterface not found

I am running EPICS 3.14.8.2, tornado 2.2, asyn 4.5, streamDevice 2.0 on mvme167 and ppc2304 CPUs with a serial port server.  I am able to connect to the serial devices with the generic serial record, but streamDevice gives me a connection error.  asynReport() shows the port disconnected until I connect with the generic serial record or turn on the trace masks.  Am I missing something in the initialization, or is there a problem with the code.
