I presume you mean a VAX/VMS operating system.  (Many VAXes run some
version of UNIX instead of VAX/VMS.)

I'm not familiar with the current state of terminal support on VAX/VMS,
but it may be helpful for you to know the following:

	There are only a few configurable options, mainly involving
	how CR and LF characters are handled, that could affect the
	behavior of the 5620 itself.

	The 5620 supports a subset of ANSI X3.64 control and escape
	sequences; DEC's terminals starting with the famous VT100
	have supported slightly different (overlapping) subsets of
	X3.64.  Depending on just what features of the terminal are
	being exploited, in some situations it is possible to get by
	by pretending that the 5620 is actually a VT100.  However,
	since it does not emulate all VT100 features, and since it
	has a different number of characters in the display, in some
	cases pretending the 5620 is a VT100 doesn't work properly.

I would think that this would be the best solution, but I don't know
exactly what form that "somthing" would take.  The 5620 user's manual
should spell out the control codes and escape sequences that it does
support, and that would serve as a guide to preparing a terminal
description in whatever form it should take.  For comparative purposes,
here is the UNIX "termcap" description that we use at BRL:

# Teletype 5620, firmware version 2.0 (8;7;5) or later
# The following SET-UP modes are assumed for normal operation:
#	DUPLEX=FULL	GEN_FLOW=ON	NEWLINE=INDEX	RETURN=CR
# Other SET-UP modes may be set for operator convenience or communication
# requirements.  This termcap description is for the Resident Terminal Mode.  No
# delays are specified; use "stty ixon -ixany" to enable DC3/DC1 flow control!
