Folks,

asyn R4-17 is now available.  Links to the new documentation, release notes and tar file can be found here:
http://www.aps.anl.gov/epics/modules/soft/asyn/

asyn is now also available via the APS Subversion repository here:
https://svn.aps.anl.gov/epics/asyn/

This is from the release notes:
*********************************************
drvAsynSerialPort
Added support for local serial ports on Windows, i.e.win32-x86 and windows-x64 architectures. Previously Windows local serial ports were only supported on the cygwin-x86 architecture.
Added support for serial line software handshake flags (ixon/ixoff/xany) on most architectures (e.g. Linux, Cygwin, Darwin, WIN32; see: man stty) and vxWorks (ixon only). Thanks to Dirk Zimoch for this.

drvAsynIPPort
Host name lookup is now deferred until port connection time. This makes startup scripts robust in the face of a device that is offline at IOC startup and has been offline for so long that it's DNS entry has been deleted.
Prevent reconnects during IOC shutdown. The IP Port exithandler runs before record scanning stops. In that interval, if a record is scanned then it will trigger a reconnect, and new connection can be shutdown without sending data, or without waiting for a reply. Some embedded TCP/IP stacks have problems dealing with this. Thanks to Michael Davidsaver for this fix.

asynRecord
Fixed asynRecord.dbd to include promptgroup for fields that need it. Removed the SOCK field and asynSocketSetup.adl; the record no longer supports creating sockets, which can easily be done with the iocsh drvAsynIPPortConfigure command.
Added IXON, IXOFF, and IXANY fields for new XON/XOFF support on serial ports. These fields were added to the asynSerialPortSetup.adl medm screen.

asynPortDriver
Added a global function, findAsynPortDriver(const char *portName), that returns a pointer to an asynPortDriver object given the asyn port name.
Added 3 new asynPortDriver methods: setUInt32DigitalInterrupt, clearUInt32Interrupt, getUInt32Interrupt. These were needed to complete the asynUInt32Digital support.

asynShellCommands
The asynOctetSetInputEos, asynOctetSetOutputEos, asynOctetShowInputEos and asynOctetShowOutputEos commands now take effect even if the port is not connected. This makes startup scripts more robust in the face of devices that are not accessible at IOC startup. Removed the unused "drvInfo" parameter from each of these functions.

devAsynXXXArray
For waveform output records the device support was always writing NELM elements, rather than NORD elements.
