AIX full screen programs such as Vi and the Devices command rely on the
terminfo database (stored in /usr/lib/terminfo) to determine the escape
sequences necessary to control a particular type of terminal.  Some other
vendors' versions of UNIX* use a similar database known as termcap that
is stored in /etc/termcap.  The problem you are experiencing is most likely
occurring because the SUN's and VAXen that you are logging into probably do not
have terminfo or termcap entries for the ibm8512, ibm8513, or ibm8514 
that you are using on your AIX PS/2.  The possible solutions include:
1) adding support for the PS/2 console to the SUN or VAXen's termcap
or terminfo files.  2) use the -e vt100 option of AIX telnet to 
cause telnet to emulate a vt100 terminal (almost every UNIX* machine will
have a terminfo or termcap entry for the vt100).  Once you login to the
remote machine, make sure your TERM environment variable is set correctly.
Under /bin/sh, use "TERM=vt100;export TERM"; under /bin/csh use
"setenv TERM vt100" to set the terminal type.  Use the env command
to verify the terminal type.

*UNIX is a trademark of AT&T.

IBM recently published a blue softbound book that contains short
descriptions of numerous products offered by other vendors.  The
book is entitled "AIX Catalog" (pretty mundane, huh?).  I'm not
sure of the order number but I think the book was published 
within the last few months.  Also, the cover sports a picture of
a spherical object containing numerous small rectangular mirrors.

AADU offers a printserving feature that is essentially transparent.
Once the AADU connection has been made (and the AIX disk appears
as drive E: or whatever on the DOS machine) you merely have to
type "printer E: LPT1" to cause all DOS print jobs (including
print-screens) to be forwarded to the AIX printer.

Me too.
