Comment 1 for bug 1741578

Also affects Base-3.16.1.

It seems that we actually stopped building the VxWorks-specific implementation of the readline code that calls ledLib, thus on VxWorks we're currently only using the basic implementation with no line editing or command-line history. This was due to a missing build configuration parameter when I reorganized the epicsReadline code (there is also a typo in the vxWorks/osdReadline.c file).

This bug also demonstrates that our basic readline implementation behaves differently than the others, in that it doesn't echo input that it receives from a script. I briefly thought about this, but decided not to fix this aspect of the problem.
