You can turn off the error messages completely with
 
asynSetTraceMask("L3", 0)
 
I don't think you can only print connection status change messages.
 
Right now the asyn trace mask bits are:
 
#define ASYN_TRACE_ERROR     0x0001
#define ASYN_TRACEIO_DEVICE  0x0002
#define ASYN_TRACEIO_FILTER  0x0004
#define ASYN_TRACEIO_DRIVER  0x0008
#define ASYN_TRACE_FLOW      0x0010

I have been thinking that it would be good to add
ASYN_TRACE_WARNING
 
which would print messages for conditions that are less severe than ASYN_TRACE_ERROR, but still not "normal" which is when ASYN_TRACE_FLOW should print.
 
I don't think that would solve your problem though, since presumably you would like to see a message on reconnect, which would not be characterized as an error or warning.

The log files of some of our IOCs are spammed with failed reconnect messages
like this:

[Fri Oct 16 09:30:15 2009]2009/10/16 09:30:15.139
asynManager::asynConnectCallback, port L3 error calling asynCommon->connect

[Fri Oct 16 09:30:21 2009]
[Fri Oct 16 09:30:21 2009]2009/10/16 09:30:21.147  L3 -1 autoConnect could

[Fri Oct 16 09:30:27 2009]2009/10/16 09:30:27.156 L3 vxiConnectPort error
gpibc1cp.mlscs.bessy.de: RPC: Remote system error - No route to host


whenever e.g. a gpib box is turned off.

Is there a way to tell asyn to shut up and output mesasages only when
connection status changes?

Cheers
Ben
