About Turbo Code

Turbo Code is an improved version of Baudot code. It sends signals to

other Turbo Code TTYs as fast as you type and allows you to interrupt

the other person at any time during a conversation. The Superprint 4425

automatically connects in Turbo Code or Baudot code, depending on

which code the other TTY is using. It only uses Turbo Code when you

connect with another Turbo Code TTY.

Turbo Code also allows you to use the special “shift” characters on the top

row of your TTY (example: @ # % ^ & * _ < >). These characters will

also work in ASCII. If your call is connected in Baudot, these characters

can not be received or printed at the other end of the line. This is yet

another example of why Turbo Code is better for TTY communication

than Baudot—especially in the day of sharing your email address.

You know you are connected in Turbo Code if a dot appears in the lower

left corner of the TTY display.

This is how the Turbo Code dot looks on the display.

Turning Turbo Code on and off + +

You can switch to Baudot code at any time by pressing + + . The

Superprint 4425 will return to using either Turbo Code or Baudot code

when you turn the unit off.

Using Turbo Code interrupt

You can interrupt the other person when he or she is typing by following

these steps:

1. Be sure you see the Turbo Code dot in the lower left corner of your

TTY display.

2. Press the interrupt key ( + ) while the other person is typing.

You will see INTERRUPT REQUESTED on the display.
