Imminent ASYN release

[Eric Norum <norume@aps.anl.gov>]

Shortly after the release of EPICS R3.14.9 I plan to release ASYN  
version 4.7.  If you have any outstanding issues that you'd like to  
have addressed (or better yet have dealt with yourself) please send  
them to me as soon as possible.

Here are the salient points from the release notes:
drvAsynSerialPort

Clean up operation on POSIX/termios systems (everything but vxWorks).  
The old mechanism was prone to polling during read operations rather  
than using the termios read timeout mechanism.

devGpib

asynRecord sets line-buffering on trace file.

drvGsIP488.c

Clean up dangling 'default' statement.

devGpib

Fixed error in GPIBACMD operations.

linuxGpib

Patches from Gasper Jansa to improve option handling.

devEpics

Fixed null pointer dereference for all device support when SCAN=I/O  
Intr and asyn port could not be found.

asynRecord

Fixed buffer overflow error when NRRD>40 and IFMT=ASCII.

asynGpib

Read method now sets return status and *eomReason properly.

drvAsynIPPort/drvAsynSerialPort

*eomReason now set to ASYN_EOM_CNT when read count has been satisfied.

Add support for UDP broadcasts. Specify "UDP*" and the network  
broadcast address in the port configuration command:
drvAsynIPPortConfigure("L0", "192.168.1.255:1234 UDP*", 0, 0, 0)

drvAsynSerialPort

Full support for new timeout semantics (timeout<0 means "wait forever  
for characters to arrive", timeout=0 means "return characters  
immediately available", timeout>0 means "return a timeout status if  
no characters are received within the specified number of seconds").
