The changes were made to simplify the API. No known low-level driver
provided 'cooked and 'raw' I/O methods. The asynInterposeEos layer
provides support for 'cooked' I/O.
Yes, you need to change the readRaw and writeRaw references in your
code to have it work with ASYN R4.10, but any changes you make will
work just as well with older versions of ASYN -- thus you should not
need to add any conditionals.

Eric,
Why have the writeRaw and readRaw interfaces been removed? This
seems to

break the rule that we should always try and retain backwards
compatible

interfaces. I am already getting complaints that asynOctet devices we

support have broken. Doing this without a cast iron justification
seems

rather strange to me. I now have to maintain code that will compile

against multiple versions of asyn and so I need a number of horrible

ifdef's.
Cheers,
