vxi11Configure

If vxiName is specified as "inst" then the driver incorrectly says that it does not block.

asynRecord

If asynRecord is attached to a port that does not implement asynOctet, then asynRecord crashes of it attempt to send/receive a message.

asynManager

• a queueRequest timeout hangs if the timeout is canceled while the timout callback is active.
• cancelRequest also has possible race conditions

The next release gaurantees that when queueRequest is called:

1. Exactly one of the following occurs:
   • queue callback is called
   • timeout callback is called
   • cancelRequest removes the request before either queue callback or timeout callback is called.
2. If either the queue or timeout callback is active when cancelRequest is called, it will not return until the callback completes.

Mac OS X (Darwin)

The RPC library on Mac OS X 10.3.3 does not handle device timeouts properly and may cause core dumps. A bug report has been filed with Apple. A workaround is to use the GNU glibc RPC/XDR routines.

vxWorks

Attempting to change the trace file to "stdout" does not work becuase vxWorks has per-task standard output streams.

EPICS Base R3.14.6

When building with EPICS Base R3.14.6 or greater, comment out the epicsInterruptibleSyscall.h and epicsInterruptibleSyscall.c lines in asyn/Makefile:

Interrupt Callback

If a user callback calls a low level driver with an infinite or very long timeout, there is no way to make the call terminate. Is there a generic way to abort the call?

Greensprings IP488

Does not support GPIB specific functions.

NI1014 VME Gpib driver

This needs to be implemented for asynDriver.

Generic EPICS device support

Think about creating generic support for connecting to EPICS records.

Network Protocols

Consider generic support for various network protocals: Modbus, etherIP, etc.
