From 1015609ac0eecb2914b15e8579917625ca43219d Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Wed, 3 Aug 2016 21:16:43 +0200 Subject: [PATCH] VSI submission: redirect terminal input through socket This is needed, because on VMS, select() can only be used on sockets. being able to use select() on all kinds of file descriptors is unique to Unix. So, the solution for VMS is to create a layer that translates input from standard input to socket communication.
