TonePad v0.1 Jan 1996
=====================

Introduction
------------

TonePad is a little utility that allows you to generate long DTMF tones from
your Psion Series 3a.

It is supplied as freeware, with OPL source in case you are interested in
modifying it.

Installation
------------

Copy TONEPAD.OPO to the \OPO\ directory on any drive.
It will appear under the RunOPL icon on the system screen.


Operation
---------

Launch TonePad by selecting its name under the RunOPL icon on the system
screen and pressing <Enter>.

TonePad displays a numeric keypad and an information panel.

Simply press the keys to generate the corresponding DTMF tone.
The tone will sound for as long as you hold the key down.


Limitations
-----------

1. There is a brief glitch every 8 secs when generating long tones.
   If this causes anyone a problem, let me know and I'll have a go
   at correcting it!

2. TonePad leaves the SND: device opened whilst it is running.
   This has the side-effect of preventing any alarms from sounding.
   So if you use your Psion as an alarm clock, remember to exit TonePad
   before going to bed at night!
   If there is sufficient interest, I'll enhance TonePad to release the
   SND: device when the Psion switches off.
