ASYN-4.7

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

ASYN release 4.7 is now on the APS EPICS web server.

This release contains a number of small enhancements and bug fixes:
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.

Peter Mueller provided code to remove/restore a device from/to the  
SRQ polling list.

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.

Fix timeout settings on RTEMS.

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").
