This currently consists of devAsyn, devAsynGeneric, and asynOctetRecord. In the next release this is likely to be replaced by asynRecord. It will have all the features of asynOctetRecord but will also support the connect,enable,autoConnect features of devAsyn and devAsynGeneric.
Signal handling is broken on EPICS base R3.14.5 and lower. This will cause core dumps when a device times out and you're using readline.
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.
This should be broken up into two drivers. One that supports termios and one that supports sockets. Details to be determined.
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?
Does not support GPIB specific functions.
This needs to be implemented for asynDriver.
Think about creating generic support for connecting to EPICS records.
Consider generic support for various network protocals: Modbus, etherIP, etc.
