DECstation

Tracker 4.44

### 4.5.3: DECstation

That port hasn't been upgraded for a loong time, so it will certainly need extensive surgery to work.

It uses a package called ``AudioFile`'. It is a public domain audio package available from DEC ``crl.dec.com`' aka 192.58.206.2, ``/pub/DEC/AF`'. the software will run on a number of platforms: Sun/NeXT/SGI/DEC. The ``AF_audio.c`' code sends the sound directly to the AudioFile server. There is but a slight problem! It Seg Faults when closing the Audio connection... dunno why, haven't been able to get rid of it! Uses 2 environment variables:

`AUDIOFILE`
  the name of the audio server to connect to for mono playback. And for the Left Channel in stereo playback. eg. ``"machine:0"`'
`AUDIORIGHT`
  the name of the audio server for the Right Channel when playing stereo.

This code is only tested for DEC 5000/20, 5000/25, Ultrix 4.2, Ultrix 4.3... so I can't vouch for how well it'll work on other machines!
