You are thinking about using the D23270S keyboard mapping for a Pericom
PA terminal. Unfortunately, these Pericoms have not got the necessary
keys for this mapping: they are missing keys on the numeric keyboard :-

		      +------+------+------+------+
		      |PF1   |PF2   |PF3   |PF4   |
		      |      |      |      |      |
		      +------+-------------+------+

This makes it not such a good idea to use this mapping.
Therefore, with regret I must ask you to choose a keyboard mapping which
is suitable for a Pericom PA.
