OK, I suceeded in emulating the P503i external keypad in software. I have
some code that sends the digits 0-9 via the parallel port of a unix board
to the phone.

Each keypress takes about 150 msec, so you can get about 8 characters per
second into the phone via this interface.

Here's a link to the source code:
