John,
 
I think that if it returns asynSuccess you should ignore the error message, because it may be stale.
 
What do you see if you turn on asynTrace and do some writes?  Does the driver claim to be writing?  What type of communication port is this?
 
Mark

Subject: connections with pasynOctetSyncIO->connect



What checks should be done to verify a connection with
pasynOctetSyncIO->connect?  I have a driver that calls this.  The return
value is asynSuccess but the pasynUser->errorMessage is "port usaxsEns
or addr -1 not connected" and we see no communication.

Thanks,
John
