It will have to be "equivalent".  The select() will not work, and I am not
aware of any other C function that will allow me to wait on two input
sources at the same time.

There does not appear to be anyway for the LIB_READLINE to do this.

The native OpenVMS I/O calls are asynchonous, so I can write a routine to do
so, but I have to look at the side effects.

Usually in OpenVMS I break up the program into ASTs at this point, with one
AST "thread" handling user I/O and another AST "thread" handling the I/O to
the network and have them coordinate their interactions through semaphores.

An AST basically is a software interrupt, in user space.  I do not know how
to express it in UNIX terms, but it is used mostly where you would use a
fork().
