Unless you had a typo in your escape sequence, The string terminator
in in 7 bit mode is $\ not $/ as you typed.  The result would be the
terminal hanging waiting for the rest of the terminal load.
Everything sent was being loaded into the F7 definition.

The programmers manual is available for the terminal.  I for one was
happy to see that the quantity of documentation that comes bundled
with the terminal was lowered.  When you buy them in quantity, not
everyone needs a programmers manual.

It is possible that you had previously locked the terminal from set-up so that
it would not accept the clear command.  If I read correctly:
$P1;1|$\ will reset the terminal so that you can then issue commands
to it.  $P0;1|....$\ would then load the keys.  And $P1;0|$\ would
then lock the keys.

I assume that you realize that the function key that you have just
loaded will send its normal key sequence when struck in an un shifted
mode.  The "down loaded" key sequence is only sent if the shift key is
simultaneously depressed while striking the function key.

$ in the above examples is the ascii escape character.
