 Program:	VAXNET
 Author:	Roger Lipsett	INTERMETRICS	April 1979.
 Rewritten by:	Robin Miller	Project Software & Development, Inc. 1981

VAXNET is a program used to transfer ASCII files over an asynchronous
communications line between two computers.  The progams supplied in
this directory allow for communications between VAX and VAX or between
VAX and RSX11M.  Two programs called F2T and T2F allow task images to
be converted into ASCII records, transferred to the other computer,
and then converted back to a task image which can be run.

This program has several enhancements over the original which include:

	o  Help available on each question by typing the ESCape key.
	o  Ability to backup to the previous question by typing the ! key.
	o  Automatic setup of both local and remote terminal ports.
	o  The ability to put output from the remote into a logfile
	   on the VAX which can then be REFORMATed and printed/edited.
	o  Terminal I/O is done in full duplex mode.
	o  Better error checking and recover when transfering files.

Several problems:

	o  occasionally the program will get stuck in a HIBERNATE state
	   or will exceed its buffer I/O quota (my count was 6).  When
	   stuck in the HIBERNATE state, it must be STOPped from another
	   terminal.
	o  when VAXNET is talking to another VAX (at 9600 baud), the XON/
	   XOFF which the terminal driver sends when the typeahead buffer
	   is almost full does not always work properly (loose characters).
	   This problem it not so bad when communicating with RSX-11M or
	   if the baud rate of the remote terminal port is less than that
	   of the local port.  The problem does not exist if the remote
	   port is at 1200 baud.
