Your mention of VMS makes me suspicious. What kind of terminal were you using?
The escape sequences you used are for xterms, and could well break any
other terminal or emulator. To be safe enclose the xterm-specific bits in
some kind of test:
case $TERM in
xterm*)
export PROMPT_COMMAND='echo -ne \
"\033]2;$LOGNAME_at_$HOSTNAME: $PWD\007\033]1;$LOGNAME@$HOST\007"'
