This note shows how to use zmodem from inside the tip program on
a NeXT to retrieve a file from another UNIX(tm) machine.

1) First of all make sure you have a version of rz (the receiving
zmodem program) that allows the -1 option.  The version I used
has the following version number:

>  rz 1.26 08-21-87 for V7/BSD by Chuck Forsberg
>  Usage:  rz [-1abeuv]            (ZMODEM Batch)


2) Next create (or edit) the .tiprc file in your $HOME directory.  This
   file should contain (at a minimum) the following line:
  
   SHELL=/bin/sh

   This line is necessary because the ~$ option of tip doesn't work with
   C-Shell but does work when using Bourne Shell (at least under NeXT 1.0).

3) Login to a remote UNIX(tm) system using tip.  Type the following commands:

  sz remotefilename
  ~$
  rz -1

The sz remotefilename command is executed on the remote machine.  The
~$ causes tip to escape back to the local machine and prompt for a local
command to run.  At this point sz will produce some output - just ignore it
and type "rz -1".

During my downloads using zmodem I found that it achieved about 225 to 230
characters per second using a 2400 baud modem.  This is a whole lot better
than the 78 or so that kermit typically achieves.
