Folks,
asyn R4-12 has been released. This is from the release notes:
asynManager
A problem was introduced in R4-11 by not starting the autoconnect
process until iocInit(), and operations that do not use the XXXSyncIO
functions thus fail before iocInit(). This means, for example, that
calls to asynSetOption() to set serial port parameters fail if done in a
startup script before iocInit(). R4-12 fixes this problem by decoupling
autoconnect operations from iocInit(). NOTE: The first call to the
pasynCommon->connect() function now happens almost immediately after
pasynManager->registerInterface() is called for the asynCommon
interface. This timing is different from all previous asyn releases, and
it means that port drivers must initialize everything required by
asynCommon->connect() before they register the asynCommon interface.
This may require minor re-ordering of the initialization sequence in
some drivers.
drvAsynSerialPort
Requests to set end-of-string values or serial port parameters are
accepted even when the port is not connected. The request takes effect
when the port is connected. This makes IOC startup more robust in the
face of network or USB to serial adapters that may be unavailable on
startup.
asynInt32Average, asynFloat64Average
If record is processed before new data have arrived (numAverage==0) set
record to UDF/INVALID, set UDF to TRUE and leave value unchanged.
