I believe HP fixed, or disallowed the use of ESC in messages because one
could send a message to a system manager which would manipulate the cursor,
place text on the line and then enter it. Thus causing the SM to execute a
program of which he did not want or have knowledge of. Security issue.

Another way to do this is would be to put an [esc]G[esc]K (move cursor to
left margin, clear remainder of line from that point) at the beginning of
everyone of your TELL messages. In that manner, the "FROM J1218/" would
appear and then instantly be erased from your screen before the remainder of
the text message is written on the line.

Unfortunately, this doesn't seem to work. Although on-line help says that
the
message may be "consisting of any string of ASCII characters", the escape
character is being translated into a simple space by some process along the
line, before it gets to the terminal/console.

The simplest way to fix the problem is of course to merely correct on-line
help, but I would be prone to allow escape characters passage. The bell
works, so someone had to make at least one exception to the apparent,
unstated rule of "printable characters only" in the TELL message.
