We are preparing for a release of ASYN. Although the changes are

few, they are important. In R4-11 operations that do not use the

XXXSyncIO functions fail before iocInit. This means, for example,

that calls to asynSetOption() to set serial port parameters fail if

done before iocInit(). R4-12 fixes this problem by decoupling

autoconnect operations from iocInit(). As well, the asynSerialPort

driver now remembers option settings and applies them when the port

connects.

We're looking for courageous folks to try the current CVS snapshot and

let us know of any problems

=========== Release Notes =============
asynManager: The autoconnect code is now decoupled from EPICS iocInit.

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 USB/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.
