exceptionConnect and exceptionDisconnect

If multiple clients must wait because of a connect or disconnect only the first one gets notified. The fix is:

diff -r1.42 asynManager.c
391,392c391,392
<     pexceptionUser  = (exceptionUser *)ellFirst(&pdpCommon->exceptionNotifyList);
<     while(pexceptionUser) {
---
>     while((pexceptionUser  =
>     (exceptionUser *)ellFirst(&pdpCommon->exceptionNotifyList))) {

POSIX (termios) local serial ports

The following patch must be applied to allow local serial ports to work on POSIX (Solaris, Linux, WIN32-cygwin) machines:

Mac OS X (Darwin)

The RPC library on Mac OSD 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.

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.
