/** FifoBBS.rexx
*
* Test of fifo-handler. A small BBS. Really small...
*
* This requires VLT or VLTjr version 5.028 or later, and
* Matt Dillon's Fifo.library and fifo-handler. Please
* install these files and mount fifo: before running this.
*
* Usage: FifoBBS [local | remote]
*
* FifoBBS, when invoked without arguments will run a fake BBS
* in the current CLI. When invoked with the "local" argument,
* it will run with a local VLT, bypassing the serial port.
* In neither of these cases will "UPLOAD" or "DOWNLOAD" work.
* When invoked with the "remote" argument, it will run as a
* real BBS, through the serial port.
*
* The BBS installs itself almost completely. All you have to
* do is assign FifoBBS: or change the BBSdevice string later on
* to the location you want. You will also need to set up VLT
* for running with its pipes on. After starting the BBS for
* for the first time, you can log on as Sysop, password
* SYSOP. It will ask you to change your password. From that
* moment on, you're in business. People can register, the
* sysop can validate them. Once on the system, type help to
* find a list of commands.
*
* Alpha 0.4 by W.G.J. Langeveld, 30 January 1991.
