Notes on Pcfsp
--------------

Pcfsp is an FSP client.  FSP ("File Service Protocol") is sometimes used in
place of FTP to transfer files over the Internet.  (FSP has certain
technical advantages over FTP.)  The instructions that come with it are
pretty good.

To configure Pcfsp, you have to edit the WATTCP.CFG file that comes with it
and set two variables in the DOS environment.  You do not need to be
connected to set up Pcfsp.

This WATTCP.CFG is a pretty minimal one.  Of course, if you already have a
working WATTCP.CFG from another application, you can just use a one-line
WATTCP.CFG here:

   include=e:\internet\wattcp.cfg

Otherwise, if you have static IP, set my_ip to your PC's IP address:

   my_ip=127.0.0.1

If you have dynamic IP, comment out that line (by placing an "#" at the
front of it) and put this instead:

   include=e:\internet\ipaddr.cfg

You will need to create IPADDR.CFG when you connect and give its path here;
see the README file on my site.

Set netmask to this (do *not* use your real netmask):

   netmask=0.0.0.0

If you have a static gateway, put in its ip address:

   gateway=127.0.0.2

Otherwise, if you have a dynamic gateway (i.e., you get a different gateway
each time you connect), either give the gateway you *usually* get or comment
out the gateway line and put this:

   include=e:\internet\gateway.cfg

Again, you will have to create GATEWAY.CFG with a batch file at connect
time and give the path of the file you make.

Once WATTCP.CFG is set up, open the PPP or SLIP connection and run
SETFSP.BAT, as the instructions say to do.  This batch file sets three
variables in the DOS environment:  FSP_HOST, FSP_PORT, and FSP_TRACE.  Now
type FVER as it says to do.  For me, it worked right off.

To connect to a different FSP server, you edit SETFSP.BAT to set FSP_HOST
and FSP_PORT to the name or IP address and port number of the server, like
so:

    SET FSP_HOST=ftp.germany.eu.net
    SET FSP_PORT=2001

A good file to get at that site is /pub/tcpip/fsp/fsp-faq, which explains
more about what FSP is about and what it's for.  If the "R's" and "I's"
annoy you, unset the FSP_TRACE variable.

Pcfsp creates a file called FSP_DIR in the directory given by the TEMP
environment variable.  If the file exists, it contains the current working
directory on the FSP site.  If you're connecting to a new site, or if you
want to go back to the root directory, delete the file.
