Making a Phone Call Using the TTY Device

iPAQ to launch the phone keypad, then turn on the phone
functions of the HP iPAQ.
2. Dial the phone number of the person you are trying to reach
who also has a TTY device connected to their phone.
3. When the phone call is answered, start typing onto the TTY
keyboard.
The letters typed into the machine are turned into electrical
signals that travel over regular telephone lines. When the
signals reach their destination (another TTY), they are
converted back into letters which appear on a display screen,
are printed out on paper, or both.
