Do not use devGpib for any new project!
I find that devGpib with the GPIBCVTIO function has be able to solve
erratic communication problems that streams has been unable to deal
with. Case in point is with a Kalmus IF-488 device were the error
message would be inserted at any point in the reply (readback) string.
Using Streams I could not devise a return string argument that would
capture all the possible error messages embedded in a normal reply
string. But , using the GPIBCVTIO function I was able to write a single
function that parsed out all possible error messages from any command
and flag it appropriately.
Currently I'm in the middle of writing a Streams support for a LM-500
Cryogenic Liquid Level Monitor but have discovered that this device will
get out of sync with it reply messages, that is part of a reply is in
one string while the other half is in another reply string. I'm
seriously considering starting over to use the GPIBCVTIO function to
clean this up.
I like Streams for the ease of creating a quick device support but have
found it difficult for devices that do not have a robust command
interface. This could be the lack of ingenuity on my part to create a
complex reply argument in Streams which devGpib seems to overcome this
short coming of mine.
So, for me, devGpib will always be considered on new projects.
