If the instrument can be opened as a Unix file, then connections
should work, as should the older Rstreams. You don't have event
driven programming in R, but you can tell your R code to run a loop
where it tries to read the next input from the instrument. If there's
nothing available, it will block until the data arrives, just like
"cat" or any other Unix utility would.
